Better to emulate pread using lseek/xread/lseek:

	off_t p = lseek(fd, offset, SEEK_SET);
	xread(fd, buf, count);
	lseek(fd, p, SEEK_SET);

If you look at the history for contrib/mmap.c you will see an
implementation like that before it was called git_mmap().

This doesn't work;I tried it before.

Care to elaborate? It worked pretty well on _all_ cygwin setups I tested 
with.
