   But you cannot safely interrupt such a blocking thread because:

1. It is VERY OS-dependent, and

2. Even on an OS that allows killing blocked threads you are guaranteed to
have problems due to insufficient cleanup. If you need to kill blocking
process make it real forked process. Or use non-blocking approach
(non-blocking sockets, e.g.)
