--- Comment #11 from Paul Clarke <pc at us dot ibm.com> ---
We use TM for a multi-producer-multi-consumer queue implementation, and ran
into the issue reported in this bug.  (I had opened bug 77681 before
discovering this report.)  This report is surprisingly old.  Is there any
chance this could get bumped to higher priority?
