I have my doubts about the usefulness of this. The hs_err content can be very large (and only gets bigger over time) and can easily overwhelm any observed "screen". If stdout and stderr are being captured by another utility, such as jtreg when running tests, then again we can easily hit buffer limits and actually lose useful information in the captured log file for stdout/stderr.

While the implementation is relatively simple I do not like adding yet another pair of flags in this area - and a CSR request is needed to do this.
