Someone please correct me if I'm wrong, but I'm under the impression 
that the main script *is* compiled, but the byte-code compiled file is 
kept in memory, and not written to disk.

That's what makes this work:
------ file1.py -----
import dis
def f():
    a = 1
    print a
dis.dis(f)
---------------------
> python file1.py
  4           0 LOAD_CONST               1 (1)
              3 STORE_FAST               0 (a)
  5           6 LOAD_FAST                0 (a)
              9 PRINT_ITEM
             10 PRINT_NEWLINE
             11 LOAD_CONST               0 (None)
             14 RETURN_VALUE
