API

@dprofile expr -- run expr which may spawn tasks on other workers, track periodic backtraces
DProfile.print(;pids = procs(), args...) -- print profile results with samples from given pids. args are the same as those for Base.Profile.print
DProfile.clear() -- clear profile data everywhere
DProfile.init(; n, delay) -- set Base.Profile.init options everywhere
