I'm still able to reproduce this problem (i.e. "cat: write error"
with coreutils 6.12 under ksh on Linux 4.9.0).

However,
Given that it is has been seven and a half years ago since the last
comment, and even then it was already acknowledged that the problem does
not happen in later versions, and it happens because ksh uses 
socketpairs instead of pipes - I'm closing this bug.

If the issue of cat(1) supporting socketpair/ECONNRESET instead of
pipes/EPIPE is still relevant, we can re-open the bug.
