Remember that you have to give it as a file:// URL with an absolute path (or
as an http:// or ftp:// URL, but file:// is easiest):

ProcessBrowser nameAndRulesFor: aProcess
will return a 3-element Array with:
(1) a descriptive name
(2) a Boolean which is true if you can safely stop or kill aProcess
(3) a Boolean which is true if you can safely debug aProcess

There are some threads you don't want to kill. Trust me on this. And in any
event, these are not the ones that are likely to be causing you problems. Try
"to kill all the non-essential processes:"
Process allInstancesDo: [ :p | | rules |
rules := ProcessBrowser nameAndRulesFor: p.
rules second ifTrue: [ p terminate ]].
SoundPlayer playerProcess ifNotNilDo: [ :p | p terminate ].

The above shouldn't require restarting anything special.
