sorry, yes. You're right.

I've now properly read the code, and I see what you're suggesting. I
may be naive in believing manual pages, but in lieu of other evidence I
do tend to go with what they say and it does explicitly mention zeroing
the values upon timeout - therefore I wouldn't have expected to see
this particular problem on Solaris 2.x.
However, it wouldn't be too hard to modify it to log the condition of
timeout being reached and an fdset not being zero.

yes, that is what I should do too.
