That is a feature actually, in order to help you debug your application,
all timers in the system are stopped. So, the rtdm task will only
return from rtdm_task_sleep when you will type "continue" in gdb.
The timer which have the XNTIMER_NOBLCK bit are not stopped, but setting
this bit cleanly will need extensions of the RTDM driver API.
