`Process`: revert `#interruptWith:`
Commit
3b02b0f1f647: Cherry-picked `Semaphore`, `EventSemaphore, `Process` and `ProcessorScheduler`
changes `Process >> #interruptWith:` but this - for not yet known reason - breaks
stx:libjava tests. This commit reverts the code to version before that commit,
fixing tests.

StringCollection is a variable sized array of lines which are strings.
WARNING:
This class is temporary (a historic leftover) - it may change or
even vanish in the future. Use OrderedCollections or other standard
classes to represent collections of strings.
StringCollection used to be called Text, but this is a very bad name
- there is something totally different also named Text in ST-80 ...
