Firefox hangs completely -- apparently blocking on a Unix semaphore. I did not do anything special, and I think this happened to me before on the same system a few days ago under similar conditions -- a long running firefox session, with many tabs (e.g. 15). Seems like a deadlock.


Reproducible: Didn't try
