Coro::Timer - timers and timeouts, independent of any event loop
SYNOPSIS
# This package is mostly obsoleted by Coro::AnyEvent.
use Coro::Timer qw(timeout);
# nothing exported by default
DESCRIPTION
This package has been mostly obsoleted by Coro::AnyEvent, the only really useful function left in here is "timeout".
$flag = timeout $seconds
This function will wake up the current coroutine after $seconds seconds and sets $flag to true (it is false initially). If $flag goes
out of scope earlier then nothing happens.
This is used by Coro itself to implement the "timed_down", "timed_wait" etc. primitives. It is used like this:
sub timed_wait {
my $timeout = Coro::Timer::timeout 60;
while (condition false) {
Coro::schedule; # wait until woken up or timeout
return 0 if $timeout; # timed out
}
return 1; # condition satisfied
}

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.
