Thanks.

Ehi, Wei. As said yesterday on IRC about the other patch:
 - this is a bugfix
 - this is a super-self contained change (all within RTDS)
 - RTDS is Experimental
 - it brings value, as it removes a subtle but annoying
   behavioral bug in the scheduler

So, I know it's late, but if still possible, I think we should have it
in 4.8.

Regards,
Dario
