The sigpipe signals we issue cause early termination in distributed exec mode.

When using distributed execution mode the subgraph scripts terminate early causing incorrect results. I was able to track the issue to the termination code used in eager.sh and dgsh_tee.sh. It seems like the sigpipe is being sent before the sockets finish writing. I commented out the code causing this in #537 .

It might also be useful to recheck the test cases that required this solution as there have been multiple fixes in autosplit and r_split recently that resolved issues related to files hanging and sigpipe signals.

Review the termination code in eager.sh and dgsh_tee.sh, along with the test cases that originally required it; issue #537 contains a related change. Reproduce distributed execution and verify that subgraph scripts no longer terminate before sockets finish writing, while the relevant autosplit and r_split cases still pass.
