taken from man shmctl:
The user must ensure that a segment is eventually
destroyed; otherwise its pages that were faulted in will
remain in memory or swap.
however, i have tested the same program under Linux and Solaris, and
Solaris didn't seem to "lose" memory, while Linux seems to. I have written
a report on the tests we've done on Linux systems and shm. I should've
RTFM, because now i know the manpages say it's "normal".
