At least for me that is going to be a big nuisance since they will clutter up every directory where I run hotspot. Would it be possible to keep hotspot.log as the default name, and have a flag which multiprocess tests can use to include the pid in the name?

I agree with Staffan. This seems to be a quite invasive change in the 
sense that it will create lots of files in our test and development 
environments.

In fact, isn't it possible for the multiprocess tests that have issues 
to just specify the LogFile as:

-XX:LogFile=hotspot_pid%p.log

That wouldn't require any changes to the VM at all.

Thanks,
Bengt
