Is that the source in your image for that method? Here's what I have:
"Wait on this semaphore for up to the given number of milliseconds,
then timeout. It is up to the sender to determine the difference
between the expected event and a timeout."
| waitingProcess wakeupProcess |
waitingProcess _ Processor activeProcess.
[(Delay forMilliseconds: (anInteger max: 0)) wait.
self resumeProcess: waitingProcess] fork.
