Description

Anomalous behavior of timer server scheduling can be observed on the output of class example "timer" : in this example 2 timers with a 2-seconds period are launched with a delay od 1 second between them. If the timers are re-scheduled using the method "rtems_timer_server_fire_after" then, one can see that the timers fire in an interleaved way but with a delay of 2 seconds between them instead of 1 second as expected.

The problem was diagnosed by Joel Sherrill to be in the timer server body. The patch provided solves this problem (add a call to _Timer_Server_process_insertions() ).
