I'm sure you could get it to work. To send printString to true simply push
true, set messageSelector to printString (there are methods to search for
strings to track down the selector) and argumentCount to 0 and send
commonSend.  There are all sorts of issues.  Is the VM at a suspension
point?  Will the stack be balanced?  What if a process switch happens during
your message?  How can you collect the result?  But these al have answers.

What are you actually trying to do?
