A system call trace would be useful.

Profile locking is not likely to be free, but it's necessary, so if we can show
that the code is as fast as it can be, this bug should be WONTFIXed.

if --disable-profilelocking  is not setted then
will not be defined MOZ_PROFILELOCKING

erm. no. you can't do that. that's asking for serious profile corruption.

Sorry for attachment to wrong bug.
I want to send it to http://bugzilla.mozilla.org/show_bug.cgi?id=240936

I am working for OOo, we use Mozilla components to access addressbooks in OOo in
nearly readonly mode.
See http://dba.openoffice.org for detail.
So we need disable profile locking. I found that there is a config option
--disable-profilelocking. But it does not work. So I need this patch.
