limitiation on memory allocation

I experimented with the values:
1) On my machine 'maxusers' doesn't influence the maximum memory
allowable for allocation for single process.
2) 'maxdsiz' - Yes, as long as I keep 'maxdsiz + maxssiz' below physical
memory size - everything is fine. Single process allocates successfully
up to 'maxdsiz'.
When tried to put 'maxdsiz' > phys mem size,
indeed the system failed to boot, in all modes:
multiuser, singleuser, safe.
So I derive from here that there is no way to cause a _single process_
on FreeBSD to allocate more than physical memory size (?)
Thank you and regards,
