This continues to happen with sks 1.1.4.

it seems that sometimes, sending a SIGHUP to my sks recon process causes
it to terminate, and other times it does not.

Is anyone else seeing this misbehavior?  I'm concerned because i'd like
to ship sks in debian with a configuration that isn't vulnerable to this
sort of intermittent shutdowns.

I also should note that the PTree does not appear to me to be corrupt.
sks recon starts back up just fine, without error.
