I resent the message.

My need for threading arises from the fact that this remote has two interfaces 
with one interrupt endpoint each. One needs to open both of them to actually 
make the device talk. So, I just create two threads and do interrupt_reads in 
each of them. It works like a charm, and should be fine in general since 
there's a one-to-one relationship thread<->endpoint. In general, all the 
patch does is release the Python Global Interpreter Lock while potentially 
blocking libhid functions are executed. This will not affect single-threaded 
applications at all, and enables multi-threaded ones.
