A new bug

If you have 4NT as your shell you can start several command windows.
In window one, execute:

  	for /L %i in (1,1,1000) fs checkservers

In window two, execute:

	for /L %i in (1,1,1000) fs getcacheparms

In window three, copy a 500MB file from AFS to a local disk

In windows four, copy a 500MB file from local disk to AFS

You will find that the fs.exe commands periodically fail as
do the copies to AFS.  Examining the fs.exe failures indicate
that one of two situations occur:

(1) either the ReadFile() in src/pioctl_nt.c Transceive() fails
     with an ERROR_NOT_SUPPORTED or

(2) the data received by the ReadFile() is invalid and the
     UnmarshallLong() function returns an error because no data
     was received.

At the moment I am at a loss to explain the cause.  There is
not report of an error in the trace dump.
