-;;; Commentary:
-;;; manages receiving a stream asynchronously, 
-;;; parsing it into transactions, and then calling
-;;; handler functions
-;;; Our basic structure is the queue/process/buffer triple.  Each entry
-;;; of the queue is a regexp/closure/function triple.  We buffer
-;;; bytes from the process until we see the regexp at the head of the
-;;; queue.  Then we call the function with the closure and the
-;;; collected bytes.
-;;; Code:
-(defun tq-create (process)
-  "Create and return a transaction queue communicating with PROCESS.
-PROCESS should be a subprocess capable of sending and receiving
-streams of bytes.  It may be a local process, or it may be connected
-to a tcp server on another machine."
-  (let ((tq (cons nil (cons process
-			    (generate-new-buffer
-			     (concat " tq-temp-"
-				     (process-name process)))))))
-    (set-process-filter process
-			(`(lambda (proc string)
-			   (tq-filter  '(, tq) string))))
