    25 // ThreadCritical is used to protect short non-blocking critical sections.

    26 // This class must use no vm facilities that require initialization.

    27 // It is used very early in the vm's initialization, in allocation

    28 // code and other areas. ThreadCritical regions are reentrant.

    29 //

    30 // Due to race conditions during vm exit, some of the os level

    31 // synchronization primitives may not be deallocated at exit. It

    32 // is a good plan to implement the platform dependent sections of

    33 // code with resources that are recoverable during process

    34 // cleanup by the os. Calling the initialize method before use

    35 // is also problematic, it is best to use preinitialized primitives

    36 // if possible. As an example:

    37 //

    38 // mutex_t  mp  =  DEFAULTMUTEX;

    39 //

    40 // Also note that this class is declared as a StackObj to enforce

    41 // block structured short locks. It cannot be declared a ResourceObj

    42 // or CHeapObj, due to initialization issues.

    44 class ThreadCritical : public StackObj {

    45  friend class os;

    46  private:

    47   static void initialize();

    48   static void release();
