Version 4.3.2:

• Remove unnecessary synchronization semaphore from BufferedAsyncFileReadStream.
• Implement BufferedAsyncFileReadStreamupTo:
• Fix underscores.
• Changed startup processing to reinitialize current OS process when image moves from one platform to another (e.g. image from Windows moved to Unix).
• Check installed OSPP version before calling pthread primitive to avoid error message when using older plugin.
• Add AttachableFileStreamsetBlocking and AttacheableFileStreamsetNonBlocking convenience methods.
• Better synchronization of buffer in BufferedAsyncFileReadStream.
• Add #killCurrentChildrenAtExit and #killOnVmExit:withSignal to arrange for child processes to be terminated on VM exit even if normal shutdown processing does not occur.
• Add accessor methods for Unix setsid(), getpgid(), setpgid(), getpgrp(), setpgrp() session management functions.
• Add modifications to StandardFileStream to package.
• Lower the priority of event handler process for AioEventHander to prevent input buffer being overloaded whens service process cannot keep up with input stream.
