-# IMPORTANT INFO:
-#
-# Consider this call:
-# func.restype = c_char_p
-# func(c_char_p("123"))
-# It returns
-# "123"
-#
-# WHY IS THIS SO?
-#
-# argument tuple (c_char_p("123"), ) is destroyed after the function
-# func is called, but NOT before the result is actually built.
-#
-# If the arglist would be destroyed BEFORE the result has been built,
-# the c_char_p("123") object would already have a zero refcount,
-# and the pointer passed to (and returned by) the function would
-# probably point to deallocated space.
-#
-# In this case, there would have to be an additional reference to the argument...
