Firstly:

In the File Manager Programmer's Guide under the File I/O Queue (6-59)
we have an interesting FIFO.  What exactly is the "rest of parameter
block".  What does it look like etc....

Secondly:

If control has passed to "toExtFS" can I assume that the first queue
entry refers to the external file system (ExtFS)?

Thirdly:

If I am smart given the slow speed of the appletalk and the asynchronous
nature of the I/O should I scan through queue and look for other
I/O request that refer to the ExtFS and maybe even violate the FIFO
approach but minimally check the "second" I/O request?
