A SPSDescriptor describes a Stored Prepared Statement. It correlates to a row in SYS.SYSSTATEMENTS. SYNCHRONIZATION: Stored prepared statements may be cached. Thus they may be shared by multiple threads. It is very hard for two threads to try to muck with an sps simultaeously because all ddl (including sps recompilation) clears out the sps cache and invalidates whatever statement held a cached sps. But it is possible for two statements to do a prepare execute statment at the exact same time, so both try to do an sps.prepare() at the same time during code generation, so we synchronize most everything except getters on immutable objects just to be on the safe side.
