In package debbugs, I try to use Emacs Lisp threads when retrieving SOAP
data from the debbugs server. However, ocaasionally I run into the error

--8<---------------cut here---------------start------------->8---
(error "Attempt to accept output from process debbugs.gnu.org locked to thread #<thread 0xc288a0>")
--8<---------------cut here---------------end--------------->8---

My work around is to advice url-http-create-request

--8<---------------cut here---------------start------------->8---
  (advice-add
   'url-http-create-request :around
   (lambda (orig-fun)
     "Set `url-http-attempt-keepalives' to nil."
     (setq url-http-attempt-keepalives nil)
     (funcall orig-fun))
   '(name debbugs-advice))
--8<---------------cut here---------------end--------------->8---

However, it would be great if soap-invoke-internal could care.

Done. I'm closing the bug, therefore.

Yes, I know it. But I cannot use it; the process is already in the
proper thread where it should be.

Best regards, Michael.
