The Python interpreter is not fully thread safe. In order to support

multi-threaded Python programs, there's a global lock that must be held by the

current thread before it can safely access Python objects. Without the lock,
|
||||
even the simplest operations could cause problems in a multi-threaded program:
|
||||
for example, when two threads simultaneously increment the reference count of
|
||||
the same object, the reference count could end up being incremented only once
|
||||
instead of twice.

multi-threaded Python programs, there's a global lock, called the :dfn:`global
