Ian Rogers commented on RVM-791:
--------------------------------
I had also been talking to Athul at Purdue about merging his biasing code. I've not heard from him recently though. I think biasing needs to be approached with caution. There are HotSpot applications that report a 30% slow down with its use as in the current HotSpot (and they have a lot more developer effort to try to get it right).

> Currently, Jikes RVM only allows for one style of locking. We'd like to be able to support multiple styles (eventually, it would be nice to have biased locking). As well, the locking code crosscuts more files than it needs to, largely for historical, rather than functional, reasons.
