fairly common to have two web server instances using same ServerRoot; that's another case to use LockFile, so that difference instances use different lock... no big deal with fcntl, big deal with flock...
I ended up not touching LockFile/ScoreboardFile in r160063. I'm just not wild about having huge swaths of commented-out directives in the httpd.conf if we intend for it to be simple. =) -- justin
