select with 0 timeout

I'm writing the front end to a game, and I noticed that calls to
select with only readhandles and a timeout of 0 often lock up. I've
seen comments in various code that say that this is due to a bug in
the 2.1.x kernels wherein if a select() gets stopped by an interrupt
it sometimes resumes with an infinite timeout, and indeed, replacing
libc select by a wrapper around ioctl(FIONREAD) fixes the problem.
Is this a known problem? Is there a patch around? Is this libc5's
fault, or is it in the kernel?
