RFR [S]: 8227527: LogDecorations should lazily resolve host name

[Thomas Stüfe]

Hi Claes,

This looks all very good.

My only remark is not directed at your patch, but I would prefer diagnostic
code like logging not to crash at a native OOM (I refer to the strdup), but
rather handle it gracefully, e.g. by just printing "???" as hostname.

Cheers, Thomas
