[svn-r11733] Purpose:
Code cleanup Description: Added some comments about the thread-specific memory for the error and function stacks. Changed H5close() to not use the function stack (since it causes it to be re-enabled after shutting it down) Changed thread-safe semaphore code to not use dynamicly allocated memory. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4 Too minor to require h5committest
