So, you've had this problem all along, then.

That should be OK. pqing(1) will dynamically increase the size of its input 
buffer as necessary -- though you might miss some input while it does.

In that case, I'll need to add the option O_TTY_INIT to the open().

I still don't understand why pqing(1) doesn't respond to the SIGTERM it's being 
sent. It should read, at most, 4096 bytes of input before checking the "done" 
flag that's set by the SIGTERM handler.
