Actually, I think I spoke too soon. It looks like reload AND graceful cause apache2 to segfault. Only a full restart or stopping/starting apache2 seem to get it going again.
Any time this happens, I see lines like the following in /var/log/syslog:
kernel: apache2[11246]: segfault at ffffffff ip b7682bd8 sp bfbf9b90 error 7 in libpthread-2.15.so[b767a000+17000]
