PHP 5.2 and PHP 4.4 use the same default memory limit - 8M, but near each internal structure in php 5.2 is bigger (zval, zend_class_entry, zend_op_array, zend_opcode, ...).this is one of the reasin to incrise default memory limit.
The second reason is new memory manager that uses sliht different symantick for memory_limit. (Memeory taken from system, instead of memory requested from malloc() library). I think we should set default memory_limit to 16M. Thanks.
