Thanks for the info.
1) I pulled the devel branch of nfs-2.6.git and tested the same setup,
with exactly the same result as previously.
2) then I added your patch on top of that, which did change something
but not really for the better: now even the restarted lock request
doesn't succeed after the interrupt.
According to my suspicion, this is an issue in the server, while both
referenced patches touch only the client.
Appended little test program which I'm trying out locking with.
