Christopher Hegarty - Sun Microsystems Ireland said the following on
> 6806649: synchronization bottleneck when constructing Thread subclasses
> The global synchronization on Thread.subclassAudits at Thread
> construction time has been discussed as a bottleneck:
> The implementation approach for this cache of subclass audits matches
> the once-similar implementations in ObjectInputStream and
> ObjectOutputStream, but since the 5056445 fix in JDKs 5.0u7 and 6, those

> Class keys) instead-- Thread should probably be changed similarly.
