Comment 4 for bug 333624

I see this on the versions of firefox 3.0.x and 3.1.x downloaded from ftp.mozilla.org. I also see it on the version of 3.1.x I built from source on the target machine with the debug option, so that I could get the traceback I posted above.

This doesn't appear to happen with the apt-get version from the ubuntu repository. It also doesn't happen with the same mozilla.org binaries on my single core Intrepid laptop. I only see the futex problem on the multicore Hardy server.

I'm guessing that there must be some compile option or firefox patch in the ubuntu binaries that are not in the mozilla.org binaries, that gets around this issue.
