However on trawling the internet I discovered a conversation  with someone else *on here* (c.s.r-pi) last year, who was finding that *sleep_us(x)* was highly inconsistent for certain (small) values of x. Sometimes taking a day to end.
 Further investigation reveals that in fact it really is a 'sleep' with the processor being put in low power mode and requiring an interrupt to 'wake it up'.
 

Why not use threads/timers, wait on a lock/semaphore rather than sleep.
But looking at PICO code samples, they commonly use sleep, so I'd be surprised if it was that bad.
