Hi,

the attached patch uses nanosecond resolution to generate the unique id for
each message of a maildir. This is necessary because I have about 2000 messages
which have the same mtime and size. I am not sure on how to properly check for
ruby 1.9 and do the right thing. Also, the user probably needs to run sup-sync
after this change. Maybe it should be implemented as a config option and be
enabled by default on new configs by sup-config? Thoughts?

Best regards,
Michael

This requires ruby 1.9 (nanosecond resolution is not available in 1.8)
