Everything you said is correct. While PHP uses mostly only Win32 APIs
(not POSIX-like) the limit could be higher but then all libraries do
not, which makes the 512 limits valid.

A ini settings could make sense. I will see when we can do it, will
most likely be 5.7 or 7.

May I ask you to open a feature request at bugs.php.net so I do not forget pls?
