At the moment, any child takes as many messages as it can up to the limits
set in the batch size parameters.
Counting the total number of messages that *can* be scanned is actually
quite an expensive operation. At the moment it only has to be done once as
messages are date-sorted then put in the batch. The file-locking operation
only has to be done once.

Changing to the method you suggest could only be done by adding them all to
the batch and then by removing all the excess ones you don't want. Which
means you need to remember what order they were added.
Possible, but messy.
