In GNU Emacs 18.57.3 of Thu Apr 11 1991 on wsrcc.com (berkeley-unix)
	Sparc-4/20 SunOS-4.1

I am seeing a subprocess timing problem that hadn't occurred previous
to my upgrading to 18.57.  I start a process (a hacked version of X11
program xgraph) and feed it some data points.  Somewhere around the
40th data point (ca. 1024 bytes) that I send to it I get an
off-the-wall error "no more processes".

This is timing related - because I can still run my program under
edebug.  It runs fine then.  My program also worked quite well for the
past year (under 18.55).

Did something change in the way input to subprocesses is done?  

    Signalling: (file-error "writing to process" "no more processes" #<process xgraph<4>>)
      send-string(#<process xgraph> "12331.9 31.8 34.5 34.0\n")
      (while ...)
      (let* ...)
