[ovirt-devel] [VDSM] Tests leaking child processes --with-leaked-processes

Hi all,
The most common test failure on travis (and when running locally)
is tests failing with EINTR:
IOError: [Errno 4] Interrupted system call
This happens because we are using zombiereaper, and it adds a signal
handler for SIGCHLD. When a test leaks a child process and the child
process terminates, the test runner get a SIGCHLD. If this happens
when the test framework is writing to stdout, the write is interrupted
and the test fail, failing the entire build.
Here is an example failure on travis:
https://travis-ci.org/oVirt/vdsm/jobs/187464715
To fix this we need to find the buggy tests (or tested code) leaking
child processes.
I added a new plugin for this here:
https://gerrit.ovirt.org/69324
(mostly stolen from https://gerrit.ovirt.org/69040)
Here is the result of running this plugin with current tests:
$ make check NOSE_WITH_LEAKED_PROCESSES=1
...
