After investigating with Lars, we found that the issue was caused by a
virus scanner that opens the temporary files generated by MPQS for
reading, which prevent PARI to rename the file.

One solution is to retry to rename the file until it succeeds.

I have made a branch bill-mpqs-rename
and a test binary

If you suffer from the MPQS prblem on Windows, please test it and tell
me whether this improves things.
