like:
// expesive memory processing ....
function cleanup()
{
posix_kill (posix_getpid(), 15) || posix_kill (posix_getpid(), 9);
}
register_shutdown_function("cleanup");
eventually, in a auto_apend file, if all the scripts are eating much mem.
IIRC, Posix support is compiled by default, so it looks like a nice
workarround for the memory problem...
I was wondering, could a SIGHUP to the current child make it to release
the memory? TERM is a bit harsh.
