Workshop suggestions

[bflanigan]

1. How would a memory leak or goroutine leak look like in pprof or the trace tool?
2. How would a cancelled context that cascades its way through "many" child goroutines look like in pprof or the trace tool?
3. Tracking down a memory leak - what are best practices for avoiding mem leaks? Provide examples of blatant and not so blatant ways to leak memory.
