Is this to say that an underlying memory allocator would return an address
from the malloc function of memory which had previously been allocated by
another process ? This seems to be somewhat chaotic for any memory
allocation, shared or not. But, assuming that the allocations are somehow
made common it seems that the initialization of the hash table in the
table_alloc routine would then reinitialize the common hash table each time
new servers are started up.
