説明(description)

(なおコメントによると, このメソッドは ConcurrentMarkSweepThread のメソッドだが JavaThread からしか呼び出されない. 現状では, 起動時に main/Primordial (Java)Thread から呼び出されるだけ. 将来的には CMS thread 自身が SurrogateLockerThread を作るようにすべきか検討する, とのこと.)

// Note: this method, although exported by the ConcurrentMarkSweepThread,
// which is a non-JavaThread, can only be called by a JavaThread.
// Currently this is done at vm creation time (post-vm-init) by the
// main/Primordial (Java)Thread.
// XXX Consider changing this in the future to allow the CMS thread
// itself to create this thread?
