The pressure relief valve was not useful for common work patterns as it forced the recalculation on many common actions such as bus expansion. This caused it to actually feel slower than with the pressure relief valve off. For most schematics, realtime is now fast enough to not need the valve and for those that are extremely complex, removing the valve helps this run more predictably (cherry picked from commit e6dbca051c330586b738bd27fec72760c1cf4d51)
