IIUC the use case would be to get hs_err.log files to stderr in case of crashes. However, if the stderr value gets truncated, then you'd be back at square one.

Still quite useful, since the most interesting information are at the top.

That said, the verbatim /proc/pid/maps dumping into hs-err has been bugging me for years. This can cause hs-err files in the GB range if address space is very fragmented. But the Oracle folks really like this feature, so...
