Correct.

There are some completely unrelated functions that also have "Handle" 
prefix, though, like HandleUploadManifestPacket() and 
HandleFunctionRequest(). Ignoring those, all the remaining functions 
that are in any way related to signal / interrupt handling and have the 
"Handle" prefix run in signal handlers.

I don't think it's worth fretting over. The only one of these functions 
that extensions should be calling is ProcessMainLoopInterrupts(), and an 
extension can easily add an compatibility #ifdef for that if they want to.

Thanks!
