Instead of maintaing state (pipe descriptors, signal handlers) across pselect-on-select invocations, set up and restore them each call. This prevents outside factors (eg a closefrom or signal handler installation) from potentially causing problems. This does result in a drop in throughput of a couple of percent on geriatric platforms without a native pselect due to the extra overhead. Tweaks & ok djm@
