Comments:
This class provides exceptions safe system DB locking. NB. The locking mechanism is NOT garuanteed to be recursive, so you can't call ReadLock twice then Unlock twice. You also can't go directly between a read lock to a write lock just by calling SysDBWriteLock(), you have to Unlock the ReadLock first.

int lockId;

BooleanT held;

True if lock is held.

SysDBReadLockC(int nlockId = 0)

~SysDBReadLockC()

void Unlock()

void Lock()
