Subject:	tmux 2.x performance regression when switching windows

Hello,

I noticed moving between tmux windows became much slower since 2.0.x when running some applications in the windows. The problems disappear if I move back to 1.9. To reproduce:
- Cygwin: CYGWIN_NT-6.1-WOW PMD 2.0.2(0.287/5/3) 2015-05-08 17:03 i686 Cygwin, Win7 64 bits.
- Start tmux and create two windows.
- In one of the windows, execute the following Go program (natively compiled, Go 1.4.2 64-bits):
"""
package main

import (
    "fmt"
    "time"
)

func main() {
    for i := 0; ; i++ {
        fmt.Println(i)
        time.Sleep(500*time.Millisecond)
    }
}
"""
- Try switching between windows
KO => it eventually succeeds but lags a lot. With 1.9, the switch is immediate.
