Description

[Andrew Halberstadt [:ahal]]

Running mach try again resulted in this traceback temporarily:

IOError: [Errno 2] No such file or directory: u'/home/ahal/.mozbuild/srcdirs/mozilla-central-abd83d18d5df/cache/taskgraph/target_task_set'

  File "/home/ahal/dev/mozilla-central/tools/tryselect/mach_commands.py", line 342, in try_again

I then ran it from another terminal session and it worked fine. Not sure what was going on here, but worth having on file.

I'm unsure of the root cause as the file should exist if generate_tasks has worked, but this should avoid errors in the meantime while we investigate.
