Trace on Variable assignment

[Torbjorn Tornkvist]

Ok, here is a possible workaround:

It is possible to write conditional breakpoints in the debugger.
However, in a complex system it may not be possible to 'stop'
the execution at a break point. The solution is to write the
conditional break point so that it sends a message somewhere
and have it always return false (i.e it won't trigger the
debugger).
