 When I have a lot of modules (150-200) loaded via bytecode, ghci gets very
 laggy, and haskeline has a tendency to go from command mode back to insert
 mode spontaneously.  For example, I'll press ctrl-[ k to get the previous
 history entry, and get a 'k' instead.  Or it will go to the previous
 entry, but when I hit 'j' it will insert a 'j'.  All of this is after some
 lag.

 The problem doesn't happen if I use up arrow, but it makes it hard to use
 ghci with lots of bytecode loaded.  The lagginess and problem don't happen
 if I load the modules as binary.

 I mostly notice this happening when getting history with 'j' and 'k', but
 if I press ctrl-[ h too quickly I get a beep and stay in insert mode.  I
 have to wait a moment after the ctrl-[ to get to command mode.

 OS X, ghc 7.8.3, I'll try to repro on linux later.
