Another caused loss of output from a program that had died (when the program was killed the output buffers were not being flushed or something). This one can be worked around by judicious sleep's before exit (I think the folks here hacked around it this way in gcc - Stan or somebody would know more). It is also fixed, but not in a released kernel.

I never saw it under Linux. But please make sure you have an expect
with my patch applied. I believe expect in RedHat 8.0 is ok.
