I don't know just _how_ many hoops cygwin jumps through for mmap, and maybe mmap under cygwin is actually perfectly fine, but at the same time I do suspect that UNIX mmap semantics are a lot harder to emulate than just a regular "pread()", so it's quite possible that by avoiding mmap you could avoid a lot of complex cygwin code. And yes, making it all work on FAT32 would obviously be a good thing. Only testing (or somebody who knows cygwin well) can tell.
