Say that external() is a function that interacts
with the world outside of a JVM (e.g., it writes
to a socket). For simplicity's sake, assume it both
influences and is influenced by the outside world.
Would a compiler ever want to reorder
* a read of a variable and a following
call to external() ?
* a call to external() and a following
write to a variable?
In these cases, I talking about a normal,
non-volatile variable.
