The attach mechanism was added in b35 and turned on by default in b37. There are however a few clean-up items that should be fixed by feature freeze:

1. The AttachListener thread is started at VM startup. On Windows this is needed, but on Solaris/Linux we can start it lazily via the Signal Dispatcher (assuming we aren't running with -XX:-ReduceSignalUsage).

2. On Solaris/Linux if the current directory is not writable then a well known file is created in the /tmp/hsperfdata_<user> directory. This is not the best place and if the AttachListener is created lazily then we can just use /tmp/.java_pid<pid>.
