22 22
23This module collection manages coroutines. Coroutines are similar to
24Threads but don't run in parallel.
25
26This module is still experimental, see the BUGS section below.

227=head1 BUGS/LIMITATIONS
228
229 - could be faster, especially when the core would introduce special
230 support for coroutines (like it does for threads).
231 - there is still a memleak on coroutine termination that I could not
232 identify. Could be as small as a single SV.
233 - this module is not well-tested.
234 - if variables or arguments "disappear" (become undef) or become
235 corrupted please contact the author so he cen iron out the
236 remaining bugs.
237 - this module is not thread-safe. You must only ever use this module from
238 the same thread (this requirement might be loosened in the future to
239 allow per-thread schedulers, but Coro::Satte does not yet allow this).
