This fixes issue #539. Basically if there is enough free memory the OS may buffer the RDB file that the slave transfers on disk from the master. The file may actually be flused on disk at once by the operating system when it gets closed by Redis, causing the close system call to block for a long time. This patch is a modified version of one provided by yoav-steinberg of @garantiadata (the original version was posted in the issue #539 comments), and tries to flush the OS buffers incrementally (every 8 MB of loaded data).
