see bug description

i'm seeing major performance problems. I've got a
clean/empty Cocoa# app and merely drop a NSSearchText onto my main
window in Interface Builder (i don't even bind it from the managed side
by attaching an outlet or action), and when i run and type into it, i
can slowly see one character show after the other, at a rate of maybe 1
per second...

The same sort of delay can be seen on just about any UI element,
including - say - clicking a button. 

it seems to me as if something is causing cpu load in the background, slowing
handling of I events.

running "top" in the background, i see "mono" at a constant 12% going up to 70%
or even 99% while i am typing.

im attaching testcase, which basicaly does nothing more but LoadNib and Run. i
built in windows vm and used following cmdline to mackpack, ftr:

macpack -n:LeopardSpeed -a:CSharp.exe -r:Interface.nib -m:cocoa



im running latest public Mono 1.2.5.1 as available for download; OSX Leopard
10.5.0. MacBook Pro 2.4GHz. system was upgraded form Tiger, where no speed
problems were noticable, before.
