 There were fixes in 1.1.2 and 1.0.4 for finalizers&unloading, so I hope
 this works now. If there are still problems, feel free to reopen it.

+I am getting some strange behavior with NAnt-0.85rc1 and Mono-1.0.5. 
+I built mono-1.0.5 and its companion packages from sources on Ubuntu
+warty.
+
+When I run NAnt, it starts up and runs but crashes intermittently
+during the execution of a build.  The crash happens at different
+points in the build when run repeatedly.  If you only had one target,
+you might miss it, but a large script, such NAnt's own buildfile, it
+crashes every time.
+
+I tried commenting out all the AppDomain.Unload calls from the NAnt
+sources but the bootstrap NAnt.exe (the shipped NAnt binary that is
+supposed to compile NAnt) crashes before I can get a complete build.
+
+I have tried setting MONO_NO_UNLOAD=1 to no avail.
+
+The build crashes three possible ways:
+
+1. "Unhandled Exception: System.NullReferenceException" and mono hangs.
+
+2. "Segmentation fault" and mono dies.
+
+3. Mono mysteriously hangs w/no message.  Process has to be killed.
+
+Sometimes, I get free(): invalid pointer (0xsome address) messages as
+well.
+
+What should I send to help you debug this problem?  It is
+nondeterministic, so I am not sure what would help.
+
+Thank you,
+Casey
