It could be that I am running out of stack space. I am on OS X, 
and non-main threads are given a very limited stack size, they 
say [1, 2]. This foreach of mine calls into itself, and for my 
test case it nests upto 52 levels deep, which may be too much. 
Core.thread allows threads to be created with specified stack 
size, but that seems to be abstracted away in std.parallelism.
