Hello,

sorry, I kept it short because I hoped, you might be able to reproduce 
it easily.

The output of http://owww.molgen.mpg.de/~buczek/autofs-demo/AAA_test.sh 
is in http://owww.molgen.mpg.de/~buczek/autofs-demo/AAA_test.log. 
Clearly the expiry stops after the first  HUP. Maps not changed. The two 
config files are also in http://owww.molgen.mpg.de/~buczek/autofs-demo/.

Thank you !
   Donald
