The biased locking putback appears to have broken the following NSK tests:

    nsk/jvmti/scenarios/hotswap/HS101/hs101t004
    nsk/jvmti/scenarios/hotswap/HS101/hs101t006

Biased locking was putback to main/baseline on 2005.06.23 and sync'ed
into service_hs_baseline on 2005.06.24. The above two tests have hung
on almost every configuration since 2005.06.24.

I ran hs101t004 on producer using the same bits as nightly (Client VM)
in a 65 minute stress loop with a 10 minute job timeout. I observed
6 failures and no passes. When I added the -XX:-UseBiasedLocking option,
I observed 21 passes and no failures.
