" - Add heap to memory manager. This should improve performance.
- Enabling it by default so that it gets tested. We should decide before
beta 2 if we want to revert back to malloc or not."

Well, it's got some testing today.. - and it didnt do too well..

I'm testing by using the php-gtk generator.php (that parses the gtk.defs 
scheme file into a (huge) php array.

a default php5 checkout. build on a P800 timesout after parsing about 
12000 lines in 300 seconds.

when I revert the change:
#define ZEND_DISABLE_MEMORY_CACHE 1

It parses and builds the file ok.. in < 100seconds..
