multi-threading itself breaks a lot of stuff (fork for example) in subtle
ways. this issue is not really something that libev can do something
about.

the solution is to not use system then, just as any other funciton that
causes problems when threading.

Don't use system or multihreading - posix is harsh, and multithreading
imposes rather draconic limitations on a program. not much that can be
doen about it. it's a pain in the ass, but libev can only use what posix
offers.
