Remove the Tk interfaces
These were a constant source of trouble. Tkinter likely has multiple memory leaks that OfflineIMAP was tickling. I never used these, so poof, goodbye.

Curses.Blinkenlights is an interface very similar to Tk.Blinkenlights,

but is designed to be run in a console window (an xterm, Linux virtual

Tk.VerboseUI (formerly known as Tk.TkUI) is a graphical interface
|
||||
that presents a variable-sized window. In the window, each
|
||||
currently-executing thread has a section where its name and current
|
||||
status are displayed. This interface is best suited to people running
|
||||
on slower connections, as you get a lot of detail, but for fast
|
||||
connections, the detail may go by too quickly to be useful. People
|
||||
with fast connections may wish to use Tk.Blinkenlights instead.
