unless there is another process who InMidstOfFilein. IMO one should use plain boring semaphores and critical section, because exceptions have effect on current process, but completely ignorant to what happens in other ones. just to test , add the following test: sema := Semaphore new. [ sema signal. self fileIn: '20 seconds asDelay wait' ] fork. sema wait. self should: (self fileIn: '20 seconds asDelay wait') raise: InMidstOfFileInErrorOrWhatever.
amazing, Guille

sema wait. self should: (self fileIn: '20 seconds asDelay wait') raise:
oops, the above is of course should be: self should: [self fileIn: '20 seconds asDelay wait'] raise: but i think you got an idea.
InMidstOfFileInErrorOrWhatever.
