I was probably the one that sent you the select() change for the number
of fds (or a diff between 1.2 and 1.2.1, rather). Anyway.. I think
you already checked wat arguments were passed to the Linux oldselect()?
It may be in the archives, but could you send them to me, so I can
try to reproduce the problem. If it's just that the emulation of
Linux' old select code is bad, it should be easily reproducible.
