Hmm.  All I can say is I'm not sure I can even remember flash hanging
since I lowered the stack limit using this nspluginwrapper patch:
	http://docs.freebsd.org/cgi/mid.cgi?20090630184146.GA39346
(btw still no words from the nspluginwrappper port maintainer about this,
or I missed them?  Cc'd again...)

 _When_ flash hung, I usually got it back to running by doing
`killall npviewer.bin' and optionally quitting ff and doing
`rm /tmp/_org_wrapper_NSPlugins_libflashplayer.so*' and then
restarting the browser.  (If you don't do that, remaining
npviewer.bin processes might interfere with later ff sessions
making flash appear more broken than it really is...)

 HTH,
