I went in debug mode and created an addon called 8thos TMC. I added about 15 custom Template Modifications to it. Saved my work and went about my business. Later on I kept getting server time-outs whenever I tried to upgrade, install or uninstall an addon. I asked my host what's going on and he said that I had too many url rewrites and addon requests. So I removed all my url rewrites of which there only about 7 and unassociated all my TMC edits from 8thos TMC, then uninstalled TMC. I am now able to upgrade, install and uninstall addons without them timing out.
