If you install Process Explorer from here:

  http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx

you will be able to display the processes in a tree-like display, so
you will see whether es.exe is a child process of Emacs.  And in frame
14, you can see the PID of the process Emacs is waiting for:

  (gdb) frame 14
  #14 0x0102ffff in status_notify (deleting_process=0x5c6f620) at process.c:6606
  6606    process.c: No such file or directory.
  (gdb) print *p
  $1 = {
    header = {
      size = 1073872914,
      next = {
	nbytes = 144,
	buffer = 0x90,
	vector = 0x90
      }
    },
    tty_name = 57358362,
    name = 95268961,
    command = 99165854,
    filter = 57358386,
    sentinel = 95441550,
    log = 57358362,
    buffer = 72508421,
    childp = 57358386,
    plist = 57358362,
    type = 57481914,
    mark = 96614195,
    status = 99296310,
    decode_coding_system = 59149866,
    decoding_buf = 20036945,
    encode_coding_system = 59149842,
    encoding_buf = 20036945,
    write_queue = 57358362,
    gnutls_cred_type = 57358362,
    pid = 3552,     <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    infd = 5,
    outfd = 10,
    tick = 16,

Then compare this PID with all the processes that are children of
Emacs, or all the processes on your system, and you will know for
sure.

Start the Process Explorer before the hang, and it will show the new
processes as they are born.
