Gee, I only have 7 MB free! I must reboot to free some memory! And that
Asterisk is using so much memory!

In fact:
1. The system has some 100MB of free memory. almost all of it is used
for caching and such.

2. Asterisk overcommits memory: it generally asks the kernel huge
ammounts of memory, but doesn't really try to use them. At least with
Linux such overcommits are not claimed at all.
