# Ensure that the current thread is ready to call the Python
# C API, regardless of the current state of Python, or of its
# thread lock. This may be called as many times as desired
# by a thread so long as each call is matched with a call to
# PyGILState_Release(). In general, other thread-state APIs may
# be used between _Ensure() and _Release() calls, so long as the
# thread-state is restored to its previous state before the Release().
# For example, normal use of the Py_BEGIN_ALLOW_THREADS/
# Py_END_ALLOW_THREADS macros are acceptable.
# The return value is an opaque "handle" to the thread state when
# PyGILState_Ensure() was called, and must be passed to
# PyGILState_Release() to ensure Python is left in the same state. Even
# though recursive calls are allowed, these handles can *not* be shared -
# each unique call to PyGILState_Ensure must save the handle for its
# call to PyGILState_Release.
# When the function returns, the current thread will hold the GIL.
# Failure is a fatal error.

# the caller, hence the use of the GILState API.)
# Every call to PyGILState_Ensure must be matched by a call to
# PyGILState_Release on the same thread.
