this is just a nonsense. the only thing program should check is data size 
limit.

man getrlimit.

RLIMIT_DATA is fine.


unices (including linux) have virtual memory. providing enough total VM is 
a job for sysadmin.

checking available memory by one program doesn't make much sense, as other 
programs are running in the same time.
