RMA: ticks_since_last_period < ticks_executed_since_last_period

[fedetula at gmail.com (Federico Tula Rovaletti)]

Hello, I'm using RTEMS 4.6.6. I have configured a number of tasks so that I
use the RMA manager for scheduling them.

Since this version doesn't have the RMA reporter builtin, I programmed one
by my own.
The problem is that I have an strange behaviour. When I use
rtems_rate_monotonic_get_status() most of the time works as I expected, but
sometimes I get for some tasks status->ticks_since_last_period <
status->ticks_executed_since_last_period but only with a difference of 1
tick..

I'd like know if this behaviour is normal due to a resolution clocks problem
or coul it evidence that something is not working properly.

Thanks in advance
