#16 Process bug - incorrect 'super' resolution

[nlang]

In very particular cases, a running process may fail
to resolve 'super.<method>' correctly. Here is such a
particular example:

Consider the class hierarchy Process <- BaseProcess <-
ExtendedBaseProcess <- SuspendProcess. BaseProcess
defines the method 'start()', which calls 'resume()'.
ExtendedBaseProcess overrides 'start()' by printing
some comments and invoking 'super.start()'. The
SuspendProcess process is to suspend. Now, when such a
suspended process is attempted to be restarted from a
different process, say a ResumeProcess, the error
occurs. When ExtendedBaseProcess.start() is executed,
super.start() is again resolved into
ExtendedBaseProcess.start() rather than
BaseProcess.start(). As a sad consequence, an endless
loop results.

Calling start() DIRECTLY (i.e.: NOT from another
process) results in normal behavior (i.e. no endless
loop).

A detailed example reproducing this bug consistently
is attached.
