after further review.... it seems the reason your patch works on a
2.4.28 kernel, is
because signalled() never returns true, even when the process is sent
the SIGSEGV signal. Why signalled() never returns true, I don't know....
but the
reason your patch did not work on a RHEL3 kernel is because signalled()
does
return true and calls to recalc_sigpending() do not reset that pending
signal....
which seems to be a bug in the NTPL-related code.... code that is not in the
2.4.28 kernel....
