Item was changed:
----- Method: Process>>signalException: (in category 'signaling') -----
signalException: anException
"Signal an exception in the receiver process...if the receiver is currently
suspended, the exception will get signaled when the receiver is resumed. If
the receiver is blocked on a Semaphore, it will be immediately re-awakened
and the exception will be signaled; if the exception is resumed, then the receiver
will return to a blocked state unless the blocking Semaphore has excess signals"
"If we are the active process, go ahead and signal the exception"
self isActiveProcess ifTrue: [^anException signal].
"Suspend myself first to ensure that I won't run away
in the midst of the following modifications."
