When I try to send a very long string to a process created with
OPEN-NETWORK-STREAM, the recipient is seeing duplication of certain characters.
In particular, I am receiving characters 0 through 8180 of the string,
followed by characters 7991 through the end of the string -- i.e., the
characters between 7991 and 8180 appear to be received twice.
(The string happens to be about 14800 characters long).


The documentation discusses a limitation of some OSs for "buffered input in
a PTY", and talks about sending an input LINE that is too long.  I don't know
if the term LINE here refers to the STRING argument of process-send-string,
or if it really refers to the subsegments of the input separated by
newlines.  (The long string I am sending is made up of many relatively
short lines -- I'm sure no INDIVIDUAL line would exceed the OS buffering
limit.)  Or maybe (I hope) the PTY limit is not an issue for processes created
with open-network-stream.

At any rate, I have been using the same design with EPOCH on the same
OS (HPUX) for years without encountering this problem, so I suspect
this is not the problem and that something else is the source.  I'm
hoping you've had other reports of problems with process-send-string
in Emacs-19 and may already know what's going on.
