example, I open konsole, run "vmstat 1" in one tab, and open another tab.
On 2.6.38-1, vmstat shows:
$ vmstat 1 40

It shows that konsole spend about 20 seconds to open a new tab. within this period, User% and Sys% are high.
On the opposite, on 2.6.37-2, konsole need only no more than 1 second to open a new tab.
