Our test suite can report success even when the Apache server crashed. The test
suite should detect httpd crashes and report failure, if only to alert people
that the apache/MPM they are using may have bugs.
I found this when running Subversion trunk@1646184 with Apache 2.4.7 with the
'event' MPM, on Ubuntu 14.04. There is a known issue with the 'event' MPM
crashing in several 2.4.x versions, fixed in later versions (>= 2.4.10 ?).

failure: if the crash happens when accepting a connection and no other threads
in the process are active then I suspect serf's retry logic may simply reconnect
to a new process.
Searching the error_log may be the only way to detect these crashes.
