Comment #4 by Tobias BOEGE:
To conclude: the warning in [1] targets cases such as this:
- you enter an event handler for a read-ready stream (like Process_Read)
- without reading any data, you call Wait.
Since the stream is still ready to be read, you will immediately re-enter the
event handler and so it goes on without doing any work.
Example code:
Private $h As Process
Public Sub Main()
$h = Shell "echo" For Read Write As "Process"
End
Public Sub Process_Read()
Wait
End
Calling Wait in an event handler will not always, not even under bad
circumstances like many events happening, lead to stack exhaustion. It's
primarily a matter of where in the event handler you use it and in which
handler. If you read a small amount of data from the process before calling
Wait, the number of recursive calls required to consume all the data in the
Process stream will be finite and, depending on how much data the process
creates, will not exhaust your stack.
Also I'm setting this bug to invalid because we even hit the rare occasion that
the solution is explicitly mentioned in the docs :-)
