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

225 | =head1 BUGS/LIMITATIONS |
|
|
226 | |
|
|
227 | - could be faster, especially when the core would introduce special |
|
|
228 | support for coroutines (like it does for threads). |
|
|
229 | - there is still a memleak on coroutine termination that I could not |
|
|
230 | identify. Could be as small as a single SV. |
|
|
231 | - this module is not well-tested. |
|
|
232 | - if variables or arguments "disappear" (become undef) or become |
|
|
233 | corrupted please contact the author so he cen iron out the |
|
|
234 | remaining bugs. |
|
|
235 | - this module is not thread-safe. You must only ever use this module from |
|
|
236 | the same thread (this requirement might be loosened in the future to |
|
|
237 | allow per-thread schedulers, but Coro::Satte does not yet allow this). |
