Description
Hi,
Today while performing batch execution I have observed that uneven distribution of test was observed across workere_ids
For example please refer below
gw1[10], gw2[9]
As per scheduler execution will abort when this happens.
Please suggest how to overcome this issue. What are the possible scenarios this type issue may occur?

Research direction
Start with the batch-execution scheduler behavior described in the issue and reproduce the uneven assignment shown by gw1[10], gw2[9]. Trace how tests are assigned across worker IDs and identify the scenarios that produce an imbalance. Done means documenting the cause and a practical way to avoid or handle the scheduler abort.
