user/test: don't stop prematurely 3360f5ab32

timermgr: strategy for using multiple timers ... e2097736fd

The logic behind this patch is as follows:

- periodic functions are currently not able to be removed, so if a
periodic wants a higher freq, we have to permanently change it
- if a one-time function wants a higher frequency, we try to find a free
timer and use that, after the function ran, we disable it again
