----------------------------------------+-----------------------------------
 patch adds a short circuit to RingBuffer::safe_read(int, void*, uint) when
 the passed fd is invalid.  No point in wasting time trying to read() from
 the fd multiple times.  I run into this when firewire creates 0 byte files
 from not being able to pull data from the STB.
