I think that's what he said -> adding the plugin a second time to the 
page and configure it to call a uncached version of your plugin only 
displaying the flashMessages. But as I said in my answer - that'll 
somewhat slow down rendering as the whole TYPO3 and extbase framework 
are initiated for that.

I'd try the hook in TSFE, in detail this hook:
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['contentPostProc-output']

In this you can replace e.g. a HTML comment with your flashMessages and 
clear the flashMessages from the session, as TYPO3 is updating/saving 
the session right after that hook.
