portalocker is not working well on network file systems. could be an issue with the with statement. check disabled for now.

Related #2278, I think.

@satra Is this something we can fix with filelock?

[satra]

@effigies - we can try. this particular issue was from a while back.

@mgxd - did you do any explicit tests for this on our slurm system? (not the docker environment. although we should add a couple of tests for filelocking on the travis test as well.

[mgxd]

No, but l can run some tests today with SoftFileLock

[effigies]

Okay. Was just skimming through old issues to see if there's anything we might throw on the 1.2.2 or 1.3.0 milestones. We've built quite a backlog again...

Closed in #3025.
