I've run into a case where pdsh is truncating results.

First a file with many lines.

$ dd if=<(yes) of=yes.out count=421083 ibs=1
$ wc yes.out
210541 210542 421083 yes.out

$ ssh server 'cat yes.out' | wc
210541 210542 421083
$ pdsh -N -R ssh -w roadrun1pa 'cat yes.out' | wc
210542 210542 421084

Now a file with one line, but many chars.
$ tr '\n' '~' < yes.out > bigyes.out
$ wc bigyes.out
0 1 421083 bigyes.out

$ ssh server 'cat bigyes.out' | wc
0 1 421083
$ pdsh -N -R ssh -w roadrun1pa 'cat bigyes.out' | wc
16 16 131184

Trivial example I know, but I do have a use case where I'm trying to pull back data that has one line with 421083 chars.
