commit fe3dfe7e38b4ad0c11ff05b7dbd0a9b1d7efc4a8 Author: David Goulet dgoulet@torproject.org Date: Wed Feb 7 10:23:24 2018 -0500

test: Bump to 10 msec gap in the monotonic test

On slow system, 1 msec between one read and the other was too tight. For instance, it failed on armel with a 4msec gap:

https://buildd.debian.org/status/package.php?p=tor&suite=experimental

Increase to 10 msec for now to address slow system. It is important that we keep this OP_LE test in so we make sure the msec/usec/nsec read aren't desynchronized by huge gaps. We'll adjust again if we ever encounter a system that goes slower than 10 msec between calls.

Fixes #25113
