It is practically impossible to make this work 100% on a local disk,
never mind over NFS. UNIX just isn't designed with this in mind.

By default stdio will use full buffering for regular files. You could
try patching squid to setbuf(IOLBF) the access log in order to get line
buffering. The file is already opened O_APPEND.

But even then, if you want a reliable solution you should probably just
log to seperate files and merge them if needed.

HTH.
