In the Unixes I know, once you've mmap'd a file, you can close the
file descriptor without losing the mapping [and you don't need the
FD to "munmap" the pages]. In fact, this is how ".so" libraries get
into your address space! So whatever limit an O/S has on simultaneous
mmap'd files per process should be the same as whatever limit there
is on simultaneous dlopen'd libraries...
