(Obviously) sounds like a memory leak.  Presumably we're allocating X
resources and never freeing them.  But since they're unused, they get
swapped out.  I suppose this means carefully auditing all X calls.  I wish
we had *slightly* higher-level X calls that did GC for us (i.e. had
finalizers to destroy objects when they're no longer in use).  It'd be
slightly problematic, since finalizers aren't guaranteed to be called at
exit, so we might leak something when we restart, but that seems like a
small danger relative to that of leaking while we run.
