Hi again ...
I don't understand _what_ is going wrong, but at least I might
have found _when_ it is happening.
Please try the attached patch and see if it prints a warning.
On my systems, no warnings are shown when everything is OK, and
a warning is always shown before 'parallel' hangs. So the condi-
tion of the "print" might bring some light into this issue.
