589 | C<AnyEvent> module - any module using it will work inside urxvt without |

|
590 | further work. The only exception is that you cannot wait on condition |

|
591 | variables, but non-blocking condvar use is ok. What this means is that you |
|
|
592 | cannot use blocking APIs, but the non-blocking variant should work. |
