Out of curiousity, what is a good (portable?) way of dealing with signals in C++? C signal handling seems to force globals on you, which is a pain especially when signal handling is a late requirement.
You might want to use a UNIX pipe for that (by calling pipe(2)). Just write(2) into a pipe (less than PIPE_BUF bytes) and select(2) on it. This is thread-safe and signal-safe and everything. Just not too speedy.

If possible I'd like to see a solution like this that works on boost's supported platforms and released as part of boost.
Are signals sensible on Windows? I thought they were important on UNIX only. Might err though.
