Description

In the scheduling loop, if the number of ackers to be scheduled along with the executor is greater than zero, and they cannot all fit, then try to fit as many ackers as possible.

To do this, fit the executor first. If this succeeds, then attempt to fit as many ackers are possible upto and including the max required as per calculation (and as low as zero). This second step should not fail.
