Open Stack

This appears to have gone away this morning. I ran clean.sh and removed
monotonic.

The next run of stack.sh installed version 0.6 of monotonic and I no longer
see this exception.

Subject:	[openstack-dev] [devstack][tempest] RuntimeError: no suitable
            implementation for this system thrown by monotonic.py



I get this when running tempest now on a devstack I installed today. I did
not have this issue on a devstack installation I did a few days ago. This
is on ubuntu 14.04 LTS.

Everything else on this system seems to be working just fine. Only
run_tempest throws this exception.

./run_tempest.sh -s; RuntimeError: no suitable implementation for this
system.

A deeper look finds this in key.log

A peek in monotonic.py finds where the exception is.

The version of monotonic is:

---
Metadata-Version: 2.0
Name: monotonic
Version: 0.5

Any suggestions on how to get around this one?
Bug?
