Output buffering during buildFrom* functions

Improves performance by ~ 20 % if there are a lot of files

Would it make more sense to wrap the foreach block in a try/catch, stop the buffering in the catch, and then re-throw the exception?

[vaind]

Yes it would. Another solution is to just create an exception (local var $ex) instead of throwing it and breaking out of foreach. At the end of the function check if (isset($ex)) throw $ex;

[kherge]

I would opt for catching the exception.

Could you please make that change?
