I saw this on USENET, and thought it might be relevant.
It is about POSIX 1.g, and its definition of select() to have
a "const" timeout arg.

I think I read on one of our mailing lists that NetBSD
doesn't depend upon a non-const arg, however our Linux
emulation may.

In any case, something that should be investigated?

Posix.1g, which is standardizing select() and poll(), add the "const"
qualifier to the "struct timeval *".  So any system that does update
this structure today, will have to change.
