Thank you for that info :)

I wrote a small test program that allocated memory in increasingly
larger chunks, and I saw no major difference with a setting of "0" or
"1", it seemed both settings allowed my program to allocate exactely the
same amount of mem before ENOMEM was returned (I can send the test
program on request).

I'll be looking forward to a setting of "2" becomming available :)
