parrallel autobuild problems

[Stefan Metzmacher]

Hi Andrew,

do you have an idea what's happening here?

$ autobuild-list-extended.sh
kseeger (running v4-4-test, 2017-01-11 09:16:08.878348793, pid 22596)
kseeger (running v4-5-test, 2017-01-11 09:15:07.197581404, pid 988241)
kseeger (running v4-6-test, 2017-01-11 09:12:20.751511218, pid 907684)
$ date
Wed Jan 11 17:26:56 CET 2017

$ tail -n 4

It seems that the samba.tests.blackbox.samba_tool_drs test somehow uses
global
state. When one user runs multiple autobuilds and all reach at least two
run samba.tests.blackbox.samba_tool_drs they get stuck.

I saw this a lot of times in the past but I wasn't able to catch it so
nicely.
