You can only have one process waiting on a given delay at a time.
Thus, if you're forking multiple processes for a single object, your
delay can't be an instance variable. Just make it a method local:
MyClass>>startNewProcess
| delay |
delay _ Delay forMilliseconds: 300.
[[
delay wait.
self doStuff
] repeat ] fork
