I have absolutely no idea of why this doesn't work. I suspect
rewinddir() is a noop on OpenIndiana if readdir() hasn't been called.
I'll revert this commit.

rewinddir() just changes a pointer, and calls - or ought to call -
lseek() on the FD. This should be fast, since no I/O is involved
(lseek() is not documented to return EINTR, for example). Releasing
the GIL has a cost :-)
