Can we step back for a moment and talk about the "Emacs is unusable"
part?  What exactly stops working for you, that you need to start
another session?  For each command that fails at this stage, please
show the error message(s), if any, that are the manifestations of the
failures.

Also, when you cannot "connect to your email", whatever that means,
please press F12, or wait until some breakpoint breaks, and show me
the contents of these two arrays:

  (gdb) p fd_info[0]@64
  (gdb) p child_procs[0]@32

Thanks.
