FWIW - in VxWorks it is possibly to crate a task with a

True, although that should not occur for tasks created using the libCom OSI routine epicsThreadCreate(), which passes the VX_FP_TASK option but not VX_PRIVATE_ENV that would turns on private environment support. I guess the main culprits for this might be vendor-supplied binary drivers that call taskSpawn() or that might use envPrivateCreate().
