What it means is that the storage was in a task that went away. When you
split, it is using the storage again.

IPCS does not display unallocated virtual pages (as they do not really exist).

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
