there's a bug but because I use a semaphore to keep track of input 
record queue len, but this semaphore is decremented twice:
- a first time in the wait operation
- a second time while actually reading an input event
whereas it should be actually only decremented once (I'm still looking 
for my worn out brown paper bag)

I'll send a fix later on today.
