Comment(by fryguybob):
It probably should be noted that even with a working `openTempFile` the
example code can still fail:
{{{
#!hs
...
(npath1, handle1) <- openTempFile dir "tmp"
hClose handle1
removeFile npath1
-- An openTempFile on another thread
createDirectory npath1
...
}}}
Using something other then the file system to ensure (with very high
probability at least) uniqueness is probably easier then tracking down all
the possible ways a `createTempDirectory` made with `openTempFile` could
fail. Perhaps using something like
[http://hackage.haskell.org/package/uuid uuid] or
[http://hackage.haskell.org/package/system-uuid system-uuid] could work.
