Using Unity 5.3.2 Same issue on a rather large Obj imported model. Working on MacBook, OS X Yosemite.
Unity freezes, no progress status, "UnwrapCL" process taking up 100% CPU. Not a memory issue.
Baking scale on already imported model was set to 0.1 before applying.
Global baking resolution was lowered to 2 texels per unit.
When you force quit unity, the UnwrapCL process still exists after restarting Unity. The object from your assets becomes useless. The already imported model in your scene states missing source.
The only fix is to delete all related objects and re-import a fresh copy of the model.

I can confirm that also 5.3.2p4 effectively hangs for several hours with certains models. Would it be possible to make this non-blocking and add some kind of progress or "alive" meter?
