-------------8<---------- Start Bug Report ------------8<----------
1. Problem Description:
When running mp2 under the winnt mpm, calls to MP_RUN_CROAK cause
the single child process to recycle, causing an interruption of
service while Apache shuts down and restarts the child process.
(See http://issues.apache.org/bugzilla/show_bug.cgi?id=36751 to
see how this originally came up)
