What you describe above is what I had thought of. Regarding large timeout in pselect: isn't that what the sigmask to pselect is for? To wait for a signal in addition to a file descriptor?

In a nutshell, it does the same to > the loop as a timer would, but without actually running a timer. That sounds like a better idea than having a separate timer...
