Is that because pooled memory is not a good strategy for dpkg and
dselect, or something intrinsic to GNU obstacks?
getting back to the two original questions...
I am assuming the small bit of code I was able to "valgrind" is not
leaking memory because, since it is still reachable, the kernel will
free it up. So, maybe sloppy code but not really a problem.
Why did valgrind use all available VM, is that normal (I simply need to
add more swap space), or something else (valgrind bug, use of
obstacks)?
I'm not a complete newbie wrt to coding, so no need to dumb things down
too much for me.
