I don't know if there are any actual guidelines for how long one can busy-wait, but I would avoid anything beyond the low two digits of micro-seconds. Waiting blocks Task execution which is necessary for the Timer and Radio (at minimum) code to work properly.
TOS1 had a TimerJiffyAsync module that behaved (sorta) like the regular TimerM, but with a 32us resolution.
