16 megs of buffer vs 600 megs of data, worst case there's never enough.

I guess it depends on how long a track is, or whether the firmware.CD hardware/media allows it to see where it left off and turn on writing right there.
Modern buffer underrun protection isn't quite that perfect, it leaves little recoverable errors on the disk. I don't think a CDR/DVDR has the angular resolution to turn on the laser right spot-on where it left off, so I think it leaves little markers for itself when it must. It can survive brief underruns,
brief being the key.

The mmap()/munmap() is neat, though, as it allows a 32 bit program to use unlimited RAM. Things mapped stay in memory even if unmapped and are available to a new map, so you can swap super-pages of a huge set of files in your limited address space.
Interesting idea.

NAME
page_util_quote - page character quoting utilities
SYNOPSIS
package require page::util::quote ?0.1?
package require snit
::page::util::quote::unquote char
::page::util::quote::quote'tcl char
::page::util::quote::quote'tclstr char
::page::util::quote::quote'tclcom char
_________________________________________________________________
DESCRIPTION
This package provides a few utility commands to convert characters into various forms.
API
::page::util::quote::unquote char
A character, as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the result
of the command.
::page::util::quote::quote'tcl char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.
::page::util::quote::quote'tclstr char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser and
will generate a human readable representation of the character in question. The string is returned as the result of this command.
The string does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.
::page::util::quote::quote'tclcom char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser when
used within a Tcl comment. The string is returned as the result of this command.
