Some of these issues could be made to Just Go Away with some code changes. For example, using mmap rather than SysV shared memory would automatically optimize your memory usage, and get rid of the double-buffering problem as well. If we could find a way to avoid using semephores proportional to the number of connections we have, then you wouldn't have to worry about that configuration parameter, either. In fact, some of this stuff might well improve our portability, too. For example, mmap is a POSIX standard, whereas shmget is only an X/Open standard. That makes me suspect that mmap is more widely available on non-Unix platforms.
