Yes, I guess that'd make sense.

The test result is different from the expected result, which might
indicate that the wrong data is returned (no overt database corruption
has happened, AFAICS). I haven't yet looked up what those tests are
actually trying to do.

Since I can't know what to expect for the non-POSIX build (it might be
that these errors are triggered someplace else), I don't know if they
are a consequence of the (at the moment rather crude) changes I made.
Also, "disk I/O error" can unfortunately mean a lot of things, not just
locking, so even that is just an hypothesis at the moment. However,
"Windows programs" are always involved since I can't switch (completely)
off the virus scanner on the build machine.

How do you know this wouldn't happen for the "normal Cygwin build? As I
said, while sqlite3 builds in this case, the testsuite doesn't. The
next step will be to try to use the testsuite from the POSIX build and
use it with the sqlite3 for Cygwin.
