from apache/src/include/ap_config.h in the linux section there's
/* flock is faster ... but hasn't been tested on 1.x systems */
/* PR#3531 indicates flock() may not be stable, probably depends on

so you should be able to -DUSE_FLOCK_SERIALIZED_ACCEPT to try it.
(flock is less desirable than fcntl in general because it requires the
lock file to be kept around for the duration of the server, you can't
unlock() it immediately after creat().)
