That's good point.  That suggests using TEMP_FAILURE_RETRY.

There might also be network file systems that produce short writes
without signals.

Maybe we should add official glibc wrappers for read/write-style
functions that retry properly?  Including vector variants, that can be
especially tricky?

Thanks,
