I believe we have some sort of memory bloat in 0.1.0.8-rc currently.

moria2 (one of the dirservers) is running on my shiny new 64 bit opteron,
and it's running at about 10% cpu pushing 900 kB/s.

But its memory footprint has been steadily growing.

I tried running it inside valgrind (which is actually possible on this
opteron -- wow), but valgrind indicated that there were no leaks.

Yet the footprint keeps growing.

I'm currently speculating that our malloc/realloc/free patterns in
buffers.c are convincing glibc not to give the memory back to the
operating system -- that is, we *are* freeing it, but glibc keeps it
around since it expects us to ask for it back soon.

Am I going mad?

Ten points to whoever finds the problem. :)
