The memory requirements are something like 128 bytes per
client that has an entry in the persistant-tepmlate cache.
If you had an extreemly large number of clients, then this
might be a reasonable ammount of memory. But I think if
you do the maths you will see that for practical purposes
the memory requirement is quite small.

needs, think about writing your own. Or starting a discussion
on what a new sheduler may look like.
