Comment(by craigcitro):
Yep, this is a race condition. I hit exactly this problem for the "second"
half of the parallel build stuff -- namely dispatching calls to gcc in
parallel. The fix there would work here: at some point before the parallel
dispatch, I walked the tree and made sure to create all the necessary
directories. The other option would be to catch and ignore the `OSError`,
but I think that's a horrible idea. Well, that's not completely true -- if
you checked the error message, and confirmed that the filename it
complained about was a directory that does now exist, it would probably be
fine to ignore it and move on.
There's nothing RH specific about this -- I think it was just bad luck.
