But one would at least expect FD_ZERO() to really clean up rfds, and
after it FD_SET() is used again, for every call of select().  And this
code works fine in 2.0 kernels, and also with 2.2 and 2.4 if I'm using
named pipe and stdin. Therefore I have strong belief problem is not
usage of select() but something else.
