291=head1 BUGS
292
293Lots. Libevent itself isn't well tested and rather buggy, and this module
294is quite new at the moment.
295
296Please note that the epoll method is not, in general, reliable in programs
297that use fork (even if no libveent calls are being made in the forked
298process). If your program behaves erratically, try setting the environment
299variable C<EVENT_NOEPOLL> first when running the program.
300
301In general, if you fork, then you can only use the EV module in one of the
302children.
