Hmm ?

Looks like it's supported when USE_SYSVSEM_SERIALIZED_ACCEPT is defined...
The problem is... it's NEVER defined :-(( At least rgrep can find EXACTLY
one place where USE_SYSVSEM_SERIALIZED_ACCEPT is used: this ifdef in mod_ssl.h
Neither configure nor mod_ssl.h itself can define it so it's not clear how
it can be used at all :-/ When -DUSE_SYSVSEM_SERIALIZED_ACCEPT was added to
CFLAGS by hand `SSLMutex: sem' was accepted but I'm not sure if it works...
I hope so since Linux SUPPORTS SysV IPC but still...
