There definitely are times when we want debugging outputs when running with -O, but we live with restarting the server in those cases. There is such a big performance benefit to not even compiling the code when -O is enabled.

+1 on making debugging and optimization should be separately selectable options.

-1 in going about it in a hurry. This should be fixed the next time we're doing major surgery on the compiler.
