Support parallel execution

[Benjamin-Loison]

It seems to be particularly the case in Benjamin_Loison/youtube_push_notifications/src/commit/a68468adbc76fd6c095901c59dcefe053ef3b57b/subscribe_callback.php#L169, as content creators seem to plan YouTube video publication at rounded times.

Related to #24, 8go/matrix-commander/issues/31, #16 and OverClock3000/issues/3.

Got the error again while in theory there is the lock.

On OverClock3000 as benjamin:

matrix-commander -m 'a'

/usr/local/bin/matrix-commander -m 'b'

flock: cannot open lock file /var/lock/matrix-commander: Permission denied

rm /var/lock/matrix-commander

rm: remove write-protected regular empty file '/var/lock/matrix-commander'? y
rm: cannot remove '/var/lock/matrix-commander': Operation not permitted

As root:

rm /var/lock/matrix-commander

does not return anything.

Then after a minute crontab notifications work again.
