  Log Message:
  -----------
  ErrorHandling: Check for EINTR and partial writes (#147595)

Calls to the posix `write` function can return -1 and set errno to
`EINTR` or perform partial writes when interrupted by signals. In those
cases applications are supposed to just try again. See for example the
documentation in glibc:
https://sourceware.org/glibc/manual/latest/html_node/I_002fO-Primitives.html#index-write

This fixes the uses in `ErrorHandling.cpp` to retry as needed.
