  22 All gc/lock/ tests do approximately the same thing. They verify that GC
  23 is appropriately synchronized with certain class of functions.

  25 - gc/lock/jni - uses JNI GetPrimitiveArrayCritical and GetStringCritical
  26 - gc/lock/jniref - uses JNI NewGlobalRef, NewLocalRef, NewWeakGlobalRef
  27 - gc/lock/malloc - uses malloc()
  28 - gc/lock/jvmti - uses JVMTI Allocate

  30 A number of threads is started. There are some threads that repeatedly
  31 enter a critical section of code where functions describe above are
  32 repeatedly called in a loop. There are also some threads that eat
  33 memory in a loop. The idea here is to force GC to crash or deadlock.
