You could do some interesting things with buffering and scheduling to make it more responsive I suppose.
interesting to know, i guess i'll see how things progress, so maybe a new distro it is

arch(1) User Commands arch(1)
NAME
arch - display the architecture of the current host
SYNOPSIS
arch [-k | archname]
DESCRIPTION
The arch utility displays the application architecture of the current host system. Due to extensive historical use of this command without
any options, all SunOS 5.x SPARC based systems will return "sun4" as their application architecture. Use of this command is discouraged.
See NOTES section below.
Systems can be broadly classified by their architectures, which define what executables will run on which machines. A distinction can be
made between kernel architecture and application architecture (or, commonly, just "architecture"). Machines that run different kernels due
to underlying hardware differences may be able to run the same application programs.
OPTIONS
-k Displays the kernel architecture, such as sun4u. This defines which specific SunOS kernel will run on the machine, and has impli-
cations only for programs that depend on the kernel explicitly (for example, ps(1)).
OPERANDS
The following operand is supported:
archname Use archname to determine whether the application binaries for this application architecture can run on the current host
system. The archname must be a valid application architecture, such as sun4, i86pc, and so forth.
If application binaries for archname can run on the current host system, TRUE (0) is returned. Otherwise, FALSE (1) is
returned.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWcsu |
+-----------------------------+-----------------------------+
SEE ALSO
mach(1), ps(1), uname(1), attributes(5)
NOTES
This command is provided for compatibility with previous releases and its use is discouraged. Instead, the uname command is recommended.
See uname(1) for usage information.
