Subject: Create a new machine when a MachineContext is used and has a definition.
X-Git-Url: https://mograsim.net/gitweb/?p=Mograsim.git;a=commitdiff_plain;h=f4c2b2357f708fce0b1a15d7d9de32fbf509e0eb

Create a new machine when a MachineContext is used and has a definition.

This might be refined in future to a somewhat more lazy creation, but
for now it fixes the bug that a machine context has no machine at the
start, and it is not clear, when else it should be created.
