Comment 1 for bug 1794224

Those builds used to be very reliable so far but recently started to "sometimes" break on:
  Failure in 'test_multiread': timeout(14) (i = 0)

I started to work on that in bug 1794224 , but it has all the same symptoms than this issue here.
- showed up recently
- build time test timeout error
- not reproducible locally (too fast?)

Although it is not doing "much" disk I/O at the time I think I'll dup and track it together with bug 1794059
