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. Dmitry.
