Actually, its the normal speed revalidation :-)

The reason Workbench does an ACTION_INHIBIT on all the drives
is to identify the disk devices on the DOS device list.  Only
disk devices are expected to respond to the ACTION_INHIBIT packet.

Under the old file system, this created a window of vunerability.
Inhibit always succeeded...even if there were outstanding locks.
(Fast File System can fail the ACTION_INHIBIT packet, btw).  So, a
WAIT after the LoadWb is probably a pretty good thing to do,
if you plan on creating files in your startup-sequence.
