Can't issue multiple cvsclient commands to cvshome server

[Alexander Taler]

Hi All, I'm having trouble talking to the cvs server on cvshome
through LibCVS.  The server returns an error for every cvs
command beyond the first on a single connection to the server.
This has not been a problem with vanilla cvs of several versions
(1.10.8, 1.11.1p1, 1.11.*, 1.12.*) that I've used locally.

I get the following error message on the second and subsequent commands:

  cvs [status aborted]: received broken pipe signal
  cvs status: Invalid reply from auth server (dissent) looking for (DONE)

Searching the cvs code, I find nothing resembling that error
message.  I'm wondering where it comes from, if it is a CVS
interaction bug, and if I can expect to encounter this problem on
other sites.

I reproduced the problem by hand also, I've included a transcript
of the cvsclient protocol exhibiting the problem below.  It uses
exactly the same command twice, and the error occurs the second
time.  (NB telnet and pserver don't work together, but netcat is
great.)

Any information or advice would be appreciated, thanks,

Alex
