Unison 2.10.2 fast update check broken?

[Marcus Picasso]

Seems that Cygwin port of the unison file synchronizer does not do the
-fastcheck very well. Transcript follows:
# Start of transcript
# creates archives for first time
$ cd /tmp ; touch a b ; /bin/unison-2.10.2 ./a ./b
...
$ touch a
$ /bin/unison-2.10.2 -fastcheck true -times -debug verbose ./a ./b
...
# now output shows that file contents is checked, ie. the "Double-check
# possibly updated file" line, which is correct, since we did a touch
$ /bin/unison-2.10.2 -fastcheck true -times -debug verbose ./a ./b
...
# BUG: outputs again the "Double-check possibly updated file" line for file
# 'b', ie. file content is checked even if no mods.
# End of transcript
Can somebody confirm / explain this behaviour? I have a large tree that I'm
synchronizing across two hard-disks, and got suspicious when re-running
synchronization takes longer than expected. The above transcript functions 
as
expected using linux or native Win32 unison builds.

Regards,
-Marcus.
