go: missing facilities in the go runtime #59998

@knz

Description

@knz

Things we need to fix/amend:

  • avoid direct writes to fd 2
  • public goroutine ID
  • multi-goroutine "task groups" with inheritable properties
  • CPU accounting (sched ticks)
  • customizable per-goroutine state
  • RAM usage accounting
  • RAM allocation errors that don't crash the entire runtime

Jira issue: CRDB-3203
