HDD.

The issue might be triggered by that, but could this be a memory
leak?.. Not necessarily in this portion of the code.

I've been running obworker through gdb and valgrind today, but no
meaningful results so far. I'll see into how to get runtime stats on
memory allocation/freeing some day soon.

In the meantime, the issue can hang a bit. If no one is able to
reproduce it, there's no reason to file a bug report.

OK, checked. The only requests are mine, 3 total for this whole
debugging session. So not related.
