SN5.0.0: "you already have project xxx open on this machine"

Examining the source, I find lock file management in snavigator/db/dbimp.c
line 521
where db_prefix is "directory/project_name".  So it appears to create a file
directory/project.lck which contains the user/pid/etc of the locking user.

I don't see any other references to file locking, besides those in this

I thought this might be the case:

It would be nice to know which bytes in the file are the lock bytes. That 
would allow a fast and nasty way to fix the problem.
