                  Issue verified by Christoph T:
                  XC license checker shares a single I2C unit to access security memory. As this access is not locked, license checks on different xc units must not run in parallel!

                  AFAIK rcX V2.0 should also be affected too, as I cannot see any lock around Drv_SecCheckLicense().

                  Probably it does never happen as the scheduler never switches to the next task (pseudo round robin from rcX V2.0 is disabled per default)
