Bug 36730: (Bug 35428 follow-up) po files (sometimes) fail to update
Under some circumstances (e.g. non-standard disk latency) po files fail
to be generated.  The output from the gulp po:update --lang xx-XX task
is than like this:

[10:01:39] 'po_update_staff' errored after 6.41 s
[10:01:39] Error: ENOENT: no such file or directory, open '/tmp/koha-5WCc9s/Koha-staff-prog.pot'

This is due to the time dependencies inside the function flush (callback)
(in the function xgettext) in gulpfile.js.  It happens that the
/tmp/koha-NNNNNN folder gets deleted before the asynchronous callback
function called by fs.readFile is completed.  The callback should copy
the content of the .pot file from /tmp/koha- to its final destination,
while, in parallel in fact, the folder inside /tmp is being removed.
This creates a race condition.

Test plan:
==========
Hard to reproduce.  But the race condition found in the code should
be obvious.
