[TYPO3-core] RFC #12498: t3lib_div::flushOutputBuffers can't work

Hi,

I did. Sorry.

Ah, now I understand. ob_end_flush() works only a single level. So the 
code we had until now was not correct.

Seems much better to me.

I'm sure it was a long and not funny process...

+1 after reading and testing (by fetching translations from TER, running 
phpunit's BE module, checking one of my own extension's AJAX response 
and running a CLI script, with and without compression).

Olly, this corrects a bug in the current version of 4.3. It does require 
an additional +1, but also your decision at to whether it goes in or not.

Cheers
