add multiprocessing unit tests, working file-descriptor based solution and OSX#11

* TH_ALLOCATOR_MAPPED_FROMFD uses an existing file descriptor for mapping (and steals it) * TH_ALLOCATOR_MAPPED_KEEPFD doesn't close the file descriptor until the mapping is freed * TH_ALLOCATOR_MAPPED_UNLINK unlinks the file immediately after mapping it to memory Also, now it's using fstat to check the file size (instead of lseek, which alters the fd state).
