[petsc-dev] [mpich-discuss] turning off MPI abort messages

[Jeff Hammond]

(dropping MPICH list)

1. Being a jerk to users is something that I learned from PETSc
developers.  Don't even pretend that Matt and Barry offer the
"customer service" to which you seem to allude.

2. I already wrote the bloody patch even though I think the feature
request was moronic.  Jim already told you guys how to fix it.  Stop
friggin' whining.  You all act like you're the greatest programmers
that the sun has ever shined upon so why don't you contribute patches
instead of griping?

3. I am not part of the MPICH team and none of you are my customers.
It's confusing to people when you suggest any other relationship than
"Jeff is a dude that responses to threads on the MPICH discuss list".
