Bug#252149: zenity is S L O W i use zenity to chose the window ma nager when running ~/.xsession, but i feel that it is unreasonably slow

[giacomo boffi]

Package: zenity
Version: 2.6.2-2
Severity: normal

 here it is a little benchmark session, comparing the time it takes
 zenity to pop-up, and the times it takes to xemacs to load, load the
 portable dump, run all initial code, display a frame and exit

 in both cases, the tests were repeated to have everything in cache, and
 results displayed are for the last tests

 zenity uses TEN times the cpu used by xemacs (oh well, it's 11.79
 times...)
