Title:
  GLib.ThreadPool is not usuable  in PyGObject

Status in The "G" Library - GLib:
  Unknown
Status in “glib2.0” package in Ubuntu:
  Triaged

Bug description:
  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)
  **
