Review Comment:
Yes you are very correct about this!
But the delay is not the correct solution. Nothing guarantees that indeed
the `net_unlock()` line will be reached before this delay runs out, no matter
how large it is. The worker can always be scheduled-out in favor of a higher
priority (and long running) task just after the `work_queue()` call.
Either the network has to be unlocked before the work is queued, or these
two must be protected by a critical section.
I am in favor of the second solution.
