[issue31725] Turtle/tkinter: NameError crashes ipython with "Tcl_AsyncDelete: async handler deleted by the wrong thread"

[Rick J. Pelleg]

Just one more issue: since it happened before I found out that the "turtle"
package already has the pre-defined short version of commands, such as
"fd()", "lt()", etc., the crashed session included four function
definitions, for "fd()", "bk()", "lt()" and "rt()", in the form of:

def fd(val):

    forward(val)
