Dear Steve,

Thanks for your detailed message and for the code to track down our socket
problem.  We will try it out later this week and let you know what we
find.  We haven't had the socket problem recently, although we keep
running into the "more than 256 open files" problem (and it would be nice
to be able to keep more 256 files open at the same time...).

It is RedHat 8.0, with the 2.4.18-18.8.0 kernel.

That's what we thought too, so we made sure to close every socket (and to
assign some non-device to the variables that held socket devices, we also
explicitly called the garbage collector).

More later,
