I'm sorry I'm not making myself clear. We are setting the breakpoint on
sigprocmask. But, maybe I'm doing it wrong. Can you give precise
instructions as to what you want me to do, from the beginning? Sorry to
be so dense.

Me too. :)

Meanwhile, in response to one of the other questions, we are using
mpm_prefork. Also, the particular problem we're seeing does not appear
related to fork(). The pattern of sigprocmask() calls is different from
the pattern you see with fork().
