Original commit message from CVS:
a couple of fixes here:
- forward eos events to all src pads, even if spider didn't connect them. this ensures that the pipeline will stay in a consistant state even when not all pads are sent data
- don't check for nonnull spider until it is actually needed.  it really is null when it has been disposed and this method is called.
