This can happen if the calling process is handling SIGCHLD. See

We ran into this in the zephyr_mirror.
(imported from commit 80fade2274714b7c2c4b9fe38c66a1db8cc63234)
The idea here is that for usages like in the zephyr mirror bot:
backoff = RandomExponentialBackoff()
while backoff.keep_going():
print "Starting zephyr mirroring bot"
try:
subprocess.call(args)
except:
traceback.print_exc()
backoff.fail()
we want it to be the case that the mirror bot running for a while counts as a
success so that the bot doesn't have a finite number of crashes over its entire
lifetime. We only want the mirror bot to stop retrying if it fails too many
times in a row.

This will allow us to substantially decrease the server-side work that
we do to support our Mirroring systems (since the personal mirrors can
request only messages that user sent) and also is what we need to
support a single-stream Zulip widget that we embed in webpages.

This way command-line scripts that use our `optparse` populator can
still specify a custom client without munging their `parser` object.

We previously sent our client type to the server as a GET/POST parameter
of "client=<something>", most commonly "client=API: Python".
We switch here to providing the same information as a User-agent header
sent on each request, which is more standards-compliant.
Also added is some data about the platform the user is using. If your
client string was set to "MyLittleZulip/1.0", the resultant string could
look something like this:
MyLittleZulip/1.0 (Ubuntu; 12.04)

Previously it only provided the list of all public streams; now it
allows one to specify any union of some of the following:
* all public streams
* all streams the user subscribed to
(the most relevant being the union of those two, which is what we want
for the "streams" page).
Or:
* all streams in realm (superuser only)
The manual task required is that when this is pushed to prod, we need
to also deploy the new sync-public-streams version to zmirror.
(imported from commit 27848b8bd136e2777f399b7d05b2fdcec35e4e21)
When we deploy this, we'll need to of course actually build and deploy
the new API tarball.
