[Mono-devel-list] AppDomain finalization time

[Jaroslaw Kowalski]

OK. I've made the tests:

Test1: Finalization of the default appdomain (a.cs).

The code prints:
=========================
creating A...
finalizing A...
0
1

...

18
19
=========================

Which means that CLR (both 1.0 and 1.1) gives the default appdomain 2
seconds to finalize its objects. When the finalizers don't finish in 2
seconds - they are terminated.

Test2: Finalization of the custom appdomain (a2.cs)

The code prints:
=========================
creating A...
testValue: 3
unloading...
finalizing A...
0
1
2
...
...
300 (still working)
...
1000 (still working)
...
6000 (still working)
...
...
(I killed it after 6700 - over 11 minutes)
=========================

MSDN docs say:

"A long period of time can pass before domain unloads because it might be
difficult to terminate executing threads."
