In the above, how about changing "Out of memory" to 
"Allocation would exceed system or user memory limit".
Thus, one would get 

$ ./largealloc
Operating system error: Cannot allocate memory
Allocation would exceed system or user memory limit

Second, provides a hint to user where to look for 
the problem.  Whatever you decide is fine with me.
