       Coro::Specific -	manage coroutine-specific variables.

	use Coro::Specific;

	my $ref	= new Coro::Specific;

	$$ref =	5;
	print $$ref;

       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 guaranteed	to be "undef". Once such a scalar has
	   been	allocated you cannot deallocate	it (yet), so allocate only
	   when	you must.

       The actual coroutine specific values do not automatically get destroyed
       when the	Coro::Specific object gets destroyed.
