  comment:         Hi there, I have noticed that the "update idletasks" is a lot slower
                   on version 9.1. Would it be possible to improve this?

                   I've been comparing the performance of this command against version
                   8.6 and these are my findings:

                   1) On 8.6 -> run `puts [time {update idletasks}]` -> 2221 microseconds
                   per iteration  2) On 9.1 -> run `puts [time {update idletasks}]` ->
                   18012 microseconds per iteration

                   It's about 8 times slower
