[platform-swt-dev] Exception consumption during DND operations

["Randy Hudson" <hudsonr@xxxxxxxxxx>]

SWT currently consumes throwables silently in some of the bowels of DND.
This seems like a bad idea since debugging such exceptions can be **very**
difficult.  Perhaps some OS cleanup is necessary, and thus the catch block,
but can those exceptions be re-thrown after the proper teardown has
completed?
