     I have found the same. When using a RT-FIFO I discovered that is 
impossible (rtl 3.0 in 2.4.1 Linux Kernel) to implement a handler to a 
FIFO and inside the handler's code ask for access to the same FIFO. 
Maybe Mr. Victor Yodaiken had implemented two FIFO in order to 
"emulates" only one.   
   The code implements a handler to a FIFO and inside the code he acess 
another one, intead of doing all this actions at once.
