It seems that DELAY always delays by a certain number of _ticks_, even
though the parameter is in milliseconds.  When you convert 16 ms to
ticks, it comes out to 0.96 ticks, while 17 ms comes out to 1.02 ticks. 
FB probably rounds up to the next highest integer number of ticks, so
"DELAY 16" delays for 1 tick, while "DELAY 17" delays for 2 ticks.  Not
exactly a bug, but there are probably better ways to design it (I'd like
to see FB^3 use the Microsecond timer to implement the DELAY statement).
