I found a problem that `cvs server' produces infinite assertion
failures when SIGPIPE is occur.
* cvs command is almost latest.
% cvs -d :fork:/home/akr/.cvsroot version
Client: Concurrent Versions System (CVS) 1.11.1.1 (client/server)
Server: Concurrent Versions System (CVS) 1.11.1.1 (client/server)
* checkout a module which is not so small. (`cvs' in this case.)
% cvs -d :fork:/home/akr/.cvsroot co cvs
cvs server: Updating cvs
U cvs/.cvsignore
U cvs/BUGS
U cvs/COPYING
...
U cvs/zlib/zlib.rc
U cvs/zlib/zutil.c
U cvs/zlib/zutil.h
* stop cvs command with SIGPIPE, then many assertion failure is
produced.
% cd cvs
% cvs log|head

* On another terminal, I could see `cvs server' processes.
