In some cases the MRP scheduler can remain blocked on an infinite loop
consuming a lot of CPU. The reason comes from the loop 'Check done
procurements'
If a new procument is created from another process (such like MTO
orders) during this loop, the process never ends.
The only way to reproduce is in debug mode:
1. Put a breakpoint on line 'Check done procurements'
2. Launch the MRP scheduler manually and stay paused on the breakpoint
3. In parrallel, create and confirm a sale order with a MTO route, this
will trigger the creation of a new procurement order in state
'Running'
4. Continue debugging step by step the scheduler and you will notice
that the loop never ends.
