Yikes!  Thanks for pointing that out, because you made me check up on a
 keyserver i'm responsible for.  It looks like zimmermann.mayfirst.org
is doing the same thing.  the sks recon process in particular now has an
RSS of 3.3g.

Sending the process a SIGHUP is not sufficient to make it clean up any
memory either.

After a restart, the recon process only consumes ~5MB of RAM.

I'll be placing sks recon under some stricter memory limits on
zimmermann now, which might mean that it crashes because of hitting
those limits.  I suspect there's a memory leak which could be worth
tracking down.
