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....

steved.
