My impression is that scalac does not like to be run in background (&), so 
I usually don't do it then.  The scala shell script wrappers used to have 
more small issues like this in the past, and are gradually getting better 
over time.  (Such as odd effects with spaces in directory names that we 
all know only too well.)
