A quick search lead me to this issue. It would appear the deadlock still
occurs.
I've been encountering it now and then, first when running singleton tests from
http://forum.dlang.org/thread/[email protected],
then when running druntime unittests (more specifically, test/shared/host)
while working on providing shared qualifiers for core.sync primitives.

At first I though it had to do with my changes to druntime, but after testing
on a clean druntime I encoutered it as well. 

The deadlock doesn't happen on every run though, so may be tricky to track
down.
It's in this piece of test/shared/src/plugin.d:

23      launchThread();
24      GC.collect();
25      joinThread();

GC.collect() simply doesn't return. I haven't investigated deeper yet. Maybe it
has something to do with GC trying to pause/resume an exiting/finished thread?
This is on 64-bit Linux.
