Note: This shows the number of threads waiting on buffer I/O.
First figure out how long the I/O is outstanding. A good way to do
so is by searching in the threads list for processes that have a
waitchannel like biowait, ogetblk or swbuf. As a rule of thumb, only
consider I/O's outstanding longer than 30 seconds (your mileage may
vary).
