I believe that to be wise. Otherwise, Python would limit its future
implementation options.
The only thing Python should guarantee is that the data structures stay
"coherent" under race conditions. In other words, there cannot be a
segmentation fault. For example, if two threads executed this code in
parallel:
global i
i = 1
i += 1
a legal end result could be that i contains the string "impossible".
