I know it's heresy but if you just want to copy files why not use the
native XCOPY? It will not suffer the performance degredation of having
to emulate the POSIX stat semantics on every file, just like the native
DIR command in a large directory does not take ages because it simply
uses FindFirstFile/FindNextFile which are fairly efficient (but do not
provide sufficient information to emulate POSIX.)
