My first thinking, seeing this hardcoded limit was also, "we need to
make it an new ini option".
So I run a few tests.
Especially the Anatol one (a bit optimized to get more unique keys
faster), and with a debug message in zend_hash.c to display max number
of collisions encountered during the run
After some time...
With around 9.2 millions of unique keys, and ~1.2GB of memory used,
the max collisions never exceeds "12".
So I really think, now, that we can go without new ini option.
