           Summary: Socket handoff deadlock
           Product: XCB
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Library
        AssignedTo: xcb at lists.freedesktop.org
        ReportedBy: linuxhippy at gmail.com
         QAContact: xcb at lists.freedesktop.org


Created an attachment (id=26950)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=26950)
simple test-case demonstrating the deadlock.

When using the new socket-handoff functionality I often encounter deadlocks
inside of xcb.

A lot of discussion happend on the xcb mailinglist, but so far nobody was able
to explain what exactly happens, nore what the problem is. It could be I am
doing something wrong, but since there is no documentation at all ... who
knows.
I tried myself to understand the problem, but my experience with posix/c is
quite limited :-/

Attached is a simple single-threaded test-case which triggers the problem.

It would be really great if this could be fixed soon, Java would like to use
self-generated protocol to speed up its rendering sooner than later ;)
