Xenix deamon -- why doesn't it die??

In response to the following:

The deamons are probably waiting for an event in the kernel (kernel sleep)
at a priority that does not allow a SIG to terminate the operation
in progress.  A device driver can put a process to sleep at a driver-selected
priority and if that number if too high (or too low? I forget), there
is no way to kill the process until the operation completes.
