Changes for version 1.05
- Found that there is a better way to set signals on p5p (thanks Tels!), using POSIX's sigaction(). Instead of just setting %SIG, we now use sigaction(). Added internal methods _set and _ignore to aid in this. This should allow signals to come through in threads::shared::cond_wait and system calls such as "gethostbyaddr".
- Fixed some documentation nits.
