[Vm-beginners] Re: Fwd: Oops - I put a halt in a startup method

[Mariano Martinez Peck]

You are lucky that since your problem is in the startup list, then the
CompiledMethod was not yet converted to machine code. Because if it was,
then the method execution does NOT go by #commonSend: but rather from a
different place. So be careful that that way you are NOT intercepting all
times such method is executed :)
