If that's the size of fd_set on your machine, then yes, this doesn't
surprise me at all. The code that calls select() is no doubt clobbering
some bit beyond the end of the fd_set array.
7.4 is designed to use poll() in preference to select() (if available),
because of previous complaints about exactly this problem. Not sure if
you want to update to 7.4 beta, but you could consider lifting the
pqWait code out of 7.4.
