[M3devel] CM3 release build regression tests not terminating

Tue Apr 28 19:39:39 CEST 2009

Hi Jay,

thanks for reverting the offending changes to the installer.
I'm sure they were working OK when I tested them locally, and they
looked innocent enough. Sigh. Perhaps not worth to pursue the installer
issues further though.

Have you found out why it hangs though? I haven't really understood
the problem yet.

Sorry for the disturbances,

Olaf
