I used your test, but had to make a bunch of objects to get collection
to happen.  GC *is* reclaiming objects still referenced by TLS and no-TLS
(shared).  So I will need to look into that some more.

Note: this is on osx and I tweaked some of the druntime code to get it
to build, so some of this might be my doing.

So I guess as a follow up, should I expect the GC to be aware of shared
globals, or are there issues there too like thread local?
