The I/O thread did not terminate nicely. Probably, the main
thread was killed somehow without proper cleanup. The I/O thread
has very high priority in order to reduce latency (essentially, it  
just monitors a set of file descriptors and cause a interrupt when
there is pending I/O). If one of the monitored file descriptors 
is closed (e.g. a pipe), then the poll loop might under certain
circumstances turn into a 'for(;;) ;' loop.

It has nothing to do with the OF loader...
