Coro::BDB - truly asynchronous bdb access
SYNOPSIS
use Coro::BDB;
use BDB;
# can now use any of the bdb requests
DESCRIPTION
This module is an AnyEvent user, you need to make sure that you use and run a supported event loop.
This module implements a thin wrapper around the BDB module: Each BDB request that could block and doesn't get passed a callback will
normally block all coroutines. after loading this module, this will no longer be the case (it provides a suitable sync prepare callback).
It will also register an AnyEvent watcher as soon as AnyEvent chooses an event loop.
The AnyEvent watcher can be disabled by executing "undef $Coro::BDB::WATCHER". Please notify the author of when and why you think this was
necessary.
This module does not export anything (unlike Coro::AIO), as BDB already supports leaving out the callback. (Unfortunately, it ties a C
context to each coroutine executing such a callback, so in the future, it might export more efficient wrappers).
SEE ALSO
BDB of course.

Coro::Specific - manage coroutine-specific variables.
SYNOPSIS
use Coro::Specific;
my $ref = new Coro::Specific;
$$ref = 5;
print $$ref;
DESCRIPTION
This module can be used to create variables (or better: references to them) that are specific to the currently executing coroutine. This
module does not automatically load the Coro module (so the overhead will be small when no coroutines are used).
A much faster method is to store extra keys into %$Coro::current - all you have to do is to make sure that the key is unique (e.g. by
prefixing it with your module name). You can even store data there before loading the Coro module - when Coro is loaded, the keys stored in
%$Coro::current are automatically attached to the coro thread executing the main program.
You don't have to load "Coro::Specific" manually, it will be loaded automatically when you "use Coro" and call the "new" constructor.
new Create a new coroutine-specific scalar and return a reference to it. The scalar is guarenteed to be "undef". Once such a scalar has
been allocated you cannot deallocate it (yet), so allocate only when you must.
BUGS
The actual coroutine specific values do not automatically get destroyed when the Coro::Specific object gets destroyed.
