[TxMt] textmate sluggish lately esp. when changing focus

[David James]

Textmate is more sluggish lately for me than in the past.  I notice it
when I switch from the terminal back to Textmate.  TM takes a little
while to respond.  Almost like it has to awakened from a good nap.  At
least it isn't grumpy afterwards.

I'm running TextMate 1.5.6 (1414)

Anyone else notice this?  Suggestions?
