I really think that SHELL ... WAIT FOR READ *should* throw an error!  
I could see adding a Shell() or Exec() function that runs a program, 
waits for it to finish, and returns its output immediately (like my 
Backtick function, but without the awfulness) but what's the point in 
having an event-based interface for a totally synchronous operation, 
especially with these hoops you need to jump through to do it?
