+Summary: Mono spawns threads by itself and freezes machine
+
+Description of Problem:
+After launching *any* Mono application (including MonoDoc or Muine or any 
+other one) and then closing the application, mono respawns itself new 
+Mono threads, each one taking up to 12 MBs of RAM. When I kill one of 
+them, one new is re-generated automatically (it is copying itself, 
+because I had even removing the /usr/bin/mono executable, and it was 
+still respawning).
+
+After a while, there are more than 20-25 Mono threads/pids there, that 
+make the machine to run out of memory and even crash completely my 
+Slackware.
+
+Previous versions of Mono did NOT have that behavior, this is a problem 
+introduced on Mono 1.0. The only thing I did different this time was to 
+simply compile Mono and its assosiated libs with the athlon-xp 
+optimizations.
+
+Steps to reproduce the problem:
+1. Run any mono app.
+2. Close that mono app.
+3. Wait 2-3 seconds, and then mono will start respawning new mono threads 
+of itself under the process group "sh". 
+
+Actual Results:
+After a while, it clongs your machine.
+
+Expected Results:
+To shut down itself and not respawn new threads.
+
+How often does this happen? 
+Everytime.
+
+Additional Information:
+Slackware 10, kernel 2.4.26, 512 MB RAM, AthlonXP, mono and its libs/apps 
+were compiled with -mcpu and -march as "athlon-xp".
