GLib.ThreadPool is not usuable in PyGObject

GLib.ThreadPool is not usuable in PyGObject as there is no way to set the function used with the threads:

Unlike documented in the GLib Reference Manual the constructor doesn't take any arguments:

>>> from gi.repository import GLib
>>> pool = GLib.ThreadPool(lambda *args: id(0), -1 , False)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: function takes at most 0 arguments (3 given)

GLib.ThreadPool has a variable 'func' but reading it results in an error:

>>> pool = GLib.ThreadPool()
>>> pool.func

** (process:11679): WARNING **: Field func: Interface type 2 should have is_pointer set
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
RuntimeError: unable to get the value

Setting it crashes the application:

>>> pool.func = lambda *args: id(0)
