All of the issues are most likely caused by a race condition in
system.web's application domain shutdown code. Namely, just before
AppDomain.Unload is called, the dynamic base directory (where the .dll
and code files created while compiling the .as?x are kept) is cleared
which may, under certain time conditions, cause the build manger (and
possibly other code) to fail because the files it expected to find are
no longer there. The commits to svn trunk, revision 128602, and to the
2.4 branch, revision 128603 should fix that.

best regards,
