Are you thinking about this code?

setup_process_coding_systems (Lisp_Object process)
{
#ifdef subprocesses
  struct Lisp_Process *p = XPROCESS (process);
  int inch = p->infd;
  int outch = p->outfd;
  Lisp_Object coding_system;

  if (inch < 0 || outch < 0)
    return;

With :nowait t now, inch/outch will never be zero here, because we've
crated the sockets, even if we haven't connected them...  So it seems
like it'll complete whatever it's doing even if those sockets aren't
connected.  Possibly.

No, that code is called in make-network-process, so it's done before the
erc.el calls set-process-coding-system, so that's fine.
