There is additional information in another bug report at
https://postgr.es/m/16827-7606aeb21d38c228%40postgresql.org

I don't really know what to do here short term - adding EINTR handling
to syscalls that traditionally never had returned EINTR (which used to
only happen for "blocking" system calls) will be a fair amount of work.

I'll also respond in the other thread, CCing you, as there's more
information there.
