problem about writeInBackgroundAndNotify

  I have downloaded the WebServer-1.2.1 example program from http://wiki.gnustep.org/index.php/WebServer. I got a problem.

When the browser client visit the server page, like http://localhost, the server didn't give any response, until timeout.

I checked the program, I found that if I change the 

"[[connection handle] writeInBackgroundAndNotify: result]" in Line 1480

to"[[connection handle] writeData: result]"

it can work.

Does anyone known why the method writeInBackgroundAndNotify cannot work in this example?
