hs-comp: VM is not exiting

[Vladimir Kozlov]

Interesting. I tested jdk7,8,9 - all behave the same (ran with -Xint). 
It hangs on some kind of synchronization:

-----------------  lwp# 42 / thread# 42  --------------------
  fffffd7fff0abbca lwp_cond_wait (681248, 681230, 0, 0)

  fffffd7c1633f098 JVM_MonitorWait () + 214
