Please don't top post on this list, and please don't quote raw email
addresses.  See https://cygwin.com/acronyms/#TOFU for a brief note on
the whys.

Out of curiosity, I wrote a short bisect script to test this behaviour;
the behaviour changed in v2.2.0-rc0-1-gfa137f6, which changed handling
of lock files; it looks like it broke your scenario as a side-effect.

However, as I say, this isn't something that was ever supposed to work;
that it did in the past was coincidence rather than design, so I don't
think you'll have any luck getting the old behaviour back.  Using
cygpath to convert between Windows and Cygwin paths, and otherwise
sticking to Linux/Cygwin-style paths for Cygwin applications and
Windows paths for Windows ones, is the correct way to go about this.
