The maximum stack depth for alloc, mutex, block, threadcreate and goroutine

//
//   - debug=N (all profiles): response format: N = 0: binary (default), N > 0: plaintext
//   - gc=N (heap profile): N > 0: run a garbage collection cycle before profiling
//   - seconds=N (allocs, block, goroutine, heap, mutex, threadcreate profiles): return a delta profile
//   - seconds=N (cpu (profile), trace profiles): profile for the given duration
//
// # Usage examples
//
// Use the pprof tool to look at the heap profile:
//

//
//	goroutine    - stack traces of all current goroutines
//	heap         - a sampling of memory allocations of live objects
//	allocs       - a sampling of all past memory allocations
//	threadcreate - stack traces that led to the creation of new OS threads
//	block        - stack traces that led to blocking on synchronization primitives
//	mutex        - stack traces of holders of contended mutexes
//
