Changes since 1.9: +14 -8 lines 

as checked through thorough tests, youngest->mtime == ctime, so ditch
the extra field.

remove some extra abstraction layer: use clock_gettime directly
instead of ts_set_from_now (what is "now" anyways)

time_to_string takes param by pointer

rename "now" into starttime (more accurate term)

randomize queue uses arc4random_uniform (prompted by deraadt@)

display debug timestamp with ns too (it's debug, so it doesn't really
matter whichever way it's done, as long as it's done)

okay millert@
