-// thread stack
-
-// Force Bsd kernel to expand current thread stack. If "bottom" is close
-// to the stack guard, caller should block all signals.
-//
-// MAP_GROWSDOWN:
-//   A special mmap() flag that is used to implement thread stacks. It tells
-//   kernel that the memory region should extend downwards when needed. This
-//   allows early versions of BsdThreads to only mmap the first few pages
-//   when creating a new thread. Bsd kernel will automatically expand thread
-//   stack as needed (on page faults).
-//
-//   However, because the memory region of a MAP_GROWSDOWN stack can grow on
-//   demand, if a page fault happens outside an already mapped MAP_GROWSDOWN
-//   region, it's hard to tell if the fault is due to a legitimate stack
-//   access or because of reading/writing non-exist memory (e.g. buffer
-//   overrun). As a rule, if the fault happens below current stack pointer,
-//   Bsd kernel does not expand stack, instead a SIGSEGV is sent to the
-//   application (see Bsd kernel fault.c).
-//
-//   This Bsd feature can cause SIGSEGV when VM bangs thread stack for
-//   stack overflow detection.
-//
-//   Newer version of BsdThreads (since glibc-2.2, or, RH-7.x) and NPTL do
-//   not use this flag. However, the stack of initial thread is not created
-//   by pthread, it is still MAP_GROWSDOWN. Also it's possible (though
-//   unlikely) that user code can create a thread with MAP_GROWSDOWN stack
-//   and then attach the thread to JVM.
-//
-// To get around the problem and allow stack banging on Bsd, we need to
-// manually expand thread stack after receiving the SIGSEGV.
-//
-// There are two ways to expand thread stack to address "bottom", we used
-// both of them in JVM before 1.5:
-//   1. adjust stack pointer first so that it is below "bottom", and then
-//      touch "bottom"
-//   2. mmap() the page in question
-//
-// Now alternate signal stack is gone, it's harder to use 2. For instance,
-// if current sp is already near the lower end of page 101, and we need to
-// call mmap() to map page 100, it is possible that part of the mmap() frame
-// will be placed in page 100. When page 100 is mapped, it is zero-filled.
-// That will destroy the mmap() frame and cause VM to crash.
-//
-// The following code works by adjusting sp first, then accessing the "bottom"
-// page to force a page fault. Bsd kernel will then automatically expand the
-// stack mapping.
-//
-// _expand_stack_to() assumes its frame size is less than page size, which
-// should always be true if the function is not inlined.
