Yes, the interruptible flag should only have an effect when the
process receives a signal while waiting on an NFS response. Maybe
it is possible that the progess is sending itself a signal? NFS
checks for SIGINT, SIGTERM, SIGHUP, SIGKILL and SIGQUIT.

If you are using the -s/soft option then that is quite different -
there are well-known effects where an unusually long delay from
the server can trigger occasional EINTR errors.
