The 400MB have nothing to do with this error; You get it when you reach
PHP's memory limit.
Remember that PHP uses quite a lot of memory for its own purposes, other
than the memory you use for your script. The data structures used by the
engine, the modules, the symbol tables (environment, etc.) and so on and so
forth - all consume additional memory. While I wouldn't estimate they take
whole 4MB, it's not impossible.
