We have up to 16k on most ssh-aware OSes (32k on most of the Linux), so today we're still a light-year away from that. The extra 40 chars ("export DYLD_LIBRARY_PATH=LD_LIBRARY_PATH") will certainly take us closer to the limit, but not by a significant amount.

Moreover, the solution I proposed will work in any cases, without having to have prior knowledge about the peer (aka ping the remote host with a uname command).

>>> Expand the coverage a little when looking at remote shells for rsh. Prior patch (r25758) works only if both ends of the rsh/ssh connection are Mac. What we really want is to use the Mac version of ld_library_path when the remote end is Mac, regardless of the OS where mpirun is executing. So add a test for system type to the remote_shell test, and set the ld_library_path name to match the remote system type.
