"dead lock detected" in Firefox

[Gary Duzan <gary%duzan.org@localhost>]

   With current/amd64 I get the message "dead lock detected" when
trying to start Firefox. It looks like I'm hitting problems with
the locking added in rtld.c 1.141 (I have 1.142). I have made the
LD_DEBUG output available at:

   Please let me know if I can help with debugging this, or if I
should send-pr it. Thanks.
