Bug #112051 - Memory exhausted

[<pa...@sq...>]

Bug 112051 is one that needs to be fixed now that 0.5 is out.

I think the problem is that SM sometimes eat a lot of memory because
variables are copied and passed to and from functions by value instead of
by reference.

To fix this, we'll have to go through all the code and identify variables
that can be passed or assigned by reference (as "&$varname"), and functions
that can return a reference instead of a value (declared as "function &funcname()").

It is likely that this will introduce several new bugs, so maybe we should
hold off doing this for a week or two, in case we need to release 0.5.1?
