We probably should have picked that up at the time. Whoops.

OK, I'll assign this to myself and figure out how to document it. Probably won't 
be today.

Duh, unfortunately pretty much the opposite:

bool(true) -> int(1) & ~0xf == 0

The first bits are reserved for the OB handler type (internal/user) and thus ignored, so flags end
up as zero, which in turn means the handler is neither removeable, nor flushable, nor cleanable.

I suspect, I could have done better.

Mike, what happens if you pass true as the "flags" parameter in 5.4+? It looks 
easier to ask you than figure out the code paths, honestly, and we need to cover 
the BC story somehow.

The following page also should be updated.

http://www.php.net/manual/en/outcontrol.constants.php

There is no description for PHP_OUTPUT_HANDLER_CLEANABLE, 
PHP_OUTPUT_HANDLER_DISABLED, PHP_OUTPUT_HANDLER_FLUSHABLE, 
PHP_OUTPUT_HANDLER_REMOVABLE, PHP_OUTPUT_HANDLER_STARTED, 
PHP_OUTPUT_HANDLER_STDFLAGS.

The list of all constants added in PHP 5.4 is found in the following instruction 
page.
http://www.php.net/manual/en/migration54.global-constants.php
