A little-known fact about PAE Xen is that you really want to use the lowmem_emergency_pool boot parameter.

e.g., lowmem_emegency_pool=16M

Each megabyte of emergency pool will allow you to guarantee to be able to support 256 processes (counted across all VMs that you are running). So the above value would be good for 4096 processes. You'll have to decide what you need to set that parameter to.
