Here's a tentative fix for Issue #118. It's tested, and relatively simple. Other enhancements, like killing the STDOUT/STDERR pump threads when their joins time out, could easily be added.
A new error code,
OUTPUTS_LEFT_OPEN_CODE = 6
, is added to theScriptError
class. Presumably, this could be tied to information in the AWS Console for the failed event, possibly containing a link to helpful documentation?
