#4889: Ignore broken pipe error when writing to a died process

---------------------------------+------------------------------------------
In readProcessWithExitCode, when child dies without reading whole input we
get a pipe error. This happens when child program is not satisfied with
input or does not need whole input. In such a case error code from the
child program is more expected.
The solution is to ignore write error (broken pipe).
For a (short) discussion of issue see thread:

Attached patch ignores output exceptions.
