Subject: (sys_read): Introduce a small delay before reading from
X-Git-Tag: emacs-19.34~625
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=341e722e0ee82bd8a870e7019d06f625c533f56e;p=emacs.git

(sys_read): Introduce a small delay before reading from
a pipe or socket to allow more data to be buffered; otherwise,
process output is read one byte at a time on fast machines
(which is slow).
