Hi Davide,
Actually the warning has been removed in newer versions of OSProcess.
I do not have time to do an update for Pharo now, but in the mean time
you can apply this change in your image to remove the notifier:
AioEventHandler>>initializeForExceptions: exceptionEventFlag readEvents:
readEventFlag writeEvents: writeEventFlag
semaphore := Semaphore new.
semaIndex := Smalltalk registerExternalObject: semaphore.
(AioPluginPresent = true) ifTrue: [
([self aioEnable: self descriptor forSemaphore: self semaIndex
externalObject: true]
on: Warning
do: [:e |
self close. "unregister the semaphore"
OSProcess trace: e messageText asString. nil])
ifNotNil:
[handlerProc := self
handleExceptions: exceptionEventFlag
readEvents: readEventFlag
writeEvents: writeEventFlag]]
HTH,
Dave
