For reasons still unknown, Linux sometimes does not open the pipes fast enough and spends ~5 seconds waiting for something to happen and then transfers control back to the program.

This seems to be mitigated by unlinking the pipes before each run.

I am still not sure what is causing this, but re-creating the pipes each
time seems to not trigger the issue.

This turned out to be a bug in Azure: https://social.msdn.microsoft.com/Forums/azure/en-US/d98713fa-8495-4d46-8ed5-e72689551837/concurrent-sudo-invocations-sometimes-block-for-5-seconds-in-ubuntu-unity?forum=WAVirtualMachinesforWindows
