Yes and no. The system needs to allocate less physical memory at startup 
than it did before, and there is no boot-time limit of the max number of
processes anymore.

Setting MAXDSIZ to 1GB without USE_TOPDOWN_VM would make any system 
run out of memory before it booted, with USE_TOPDOWN_VM it's not
affected at all.
