I've now upgraded to Unison 2.17-1 on both the Desktop and the Laptop,
and confirmed that "unison -version" produces "unison version 2.17.1" on
both boxes. Also, other output, such as the regeneration of databases,
leads me to feel confident that it is actually running version 2.17,
even though version 2.9.20 is still installed. (For those following
along, this required manually setting the unison.exe symlink in
/etc/alternatives to point to the new version rather than the old version.)
In any case, the problems continue nearly identically with the new
version. I've attached the tail of the -debug 'all' output for the case
of one file (which hangs). The case with multiple files in a "real"
directory is also nearly identical, though the exception has of course
changed line numbers. It's now:
> Uncaught exception File "/home/aschulma/usr/cygwin/unison2.17/unison2.17-2.17.1/
> .build/remote.ml", line 530, characters 2-8: Assertion failed
I hope that's of use; let me know if there's any other debugging info I
can provide.
Thanks much,

P.S. In reference to the "-maxthreads 1" option bug I mentioned in
version 2.9.20 -- this seems to be fixed in version 2.17, and works
properly. When I specify "-maxthreads 1" on the "real" directory, it
now tries to send exactly one file at a time, and thus hangs.

(At that point, it simply hangs and does nothing.)
