package main
// Gc_latency is a modified version of a program that tickled multiple
// latency glitches in the Go GC/runtime. This version reports the time
// of the worst observed glitches so that they can be easily located in
// a trace file and debugged. This program can also be run as a benchmark
// to allow easier automated performance monitoring; the benchmark doesn't
// report worst case times because those are too noisy.
// Usage:
// gc_latency [flags]
// Flags (as main):
// -fluff
// insert 'fluff' into allocation runs to break up sweeps
// -how string
// how the buffer is allocated = {stack,heap,global} (default "stack")
// -trace string
// name of trace file to create
func main() {
howAllocated, doFluffFlag := flags()
lb := &LB{howAllocated: howAllocated, doFluff: doFluffFlag}
