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

[Super user]

	Running Xenix 386 and recently installed an Irwin tape backup
unit.  Have noticed as many as 3 deamons running at the same time for
the tape unit.  Can't seem to kill any or all of them.  It's not really
necessary to kill them but I'm more curious about why they don't die.
Does one restart the other if one dies .. the pid remains the same after
a kill. Please enlighten me.
