Currently they'll just sit around and sit around and we'll keep error on reading them.

patch

99% sure this .remove will fail on windows since the file is still open. Should add a testcase

Since the stream is closed, this _might_ work. However, indeed, a testcase should remove all doubt.
We're going to need the ability to write fake ping files in test_TelemetryPing.js; we might as well have a function for just doing it.

Closing streams appears to be idempotent, so making sure the stream is closed prior to deleting the file shouldn't cause any problems.

This became much easier when I realized I didn't have to shoehorn it into the ping/response logic earlier in the file.

part 2 - delete ping files if there's an error whilst reading them

This is good. We should however record success/fail ratios here.

part 3 - add tests

This looks good, but as I mentioned above we should record success/failure in a histogram and check the histogram gets recorded correctly in the testcase. Please post that as a followup patch.

I can add more complete checking of the contents of the histogram if you like, but it didn't seem worth it.
