Hm, maybe your process receives a signal or the thread is somehow interrupted.

Then you're probably catch an exception somewhere without rethrowing
or reporting it.

Laughing is usually not my reaction to this kind of mess...

You are doing at least one mistake: you #select with a timeout but do
not check return values.  With a timeout #select might return without
anything to read - simply because time has passed.

Also, as I said, I'd start with the regular #read and not use #sysread.
