nc_test_run_diskless2 timeouts on 4.9.0

[ArchangeGabriel]

While trying to build the 4.9 release on Arch, I’ve seen one unexpected test failure:

95/244 Testing: nc_test_run_diskless2
95/244 Test: nc_test_run_diskless2

Not sure what fails actually, it just timeouts.

Can you provide information about how you're configuring when cmake is invoked, the platform, etc? I'm trying to replicate this but cannot.

Merging #2319 might fix this.

I can confirm, cherry-picked on top of 4.9.0 and…

        Start  95: nc_test_run_diskless2
