Yeah, I wondered if the problems were (just) thread-related. No, I'm not 
using threads. The signal is just something sent by another ("shell") 
application or possibly triggered by the users. I've implemented a sort 
of poor-man's interprocess communication (because the complexity of real 
IPC is probably too great compared to the benefits in this particular 
case) via config file updates and the HUP signal; SIGHUP is simply 
interpreted as meaning "please reread your config files", just like it 
is for some of the traditional Unix/Linux server processes. (Actually, 
I've been thinking about using FAM instead, but that's a different 
discussion entirely. And maybe I'd have to address these signalling 
issues in that case, too.)
