Xen devel - Apr 2008 - Why 16KB stack size on x86 in Xen hypervisor?

What is the need of having stack size in Xen to be 16KB and 32KB on x86_64 arch?
Please note i mean in Xen hypervisor not in domain0.

Is this because we keep cpuinfo with a stack frame in Xen hypervisor
and thus need a bigger stack size?

Kindly correct me if i am wrong somewhere.

thanks in advance for any help or pointers in the correct direction
