input: python.exe hot-backup.py d:/svn d:/svn_backup >>

hot-backup.log output with errors:
Beginning hot backup of 'd:/svn'.
Youngest revision is 9755
Backing up repository to 'd:/svn_backup\svn-9755'...
Unable to backup the repository.

hot-backup.log output with no errors:
Beginning hot backup of 'd:/svn'.
Youngest revision is 9853
Backing up repository to 'd:/svn_backup\svn-9853'...
Removing old backup: d:/svn_backup\svn-9424

It fails roughly 25% of the time, so pretty hard to reliably reproduce. Any
way to get more debugging info from the hotcopy command?
