213 * management, the mob is divided into memory blocks. Each memory block
214 * will hold queries of the same type. Multiple memory blocks can be allocated

217 * Currently each memory block is of 184 bytes. We support up to 128

221 * queries. That seems reasonable for now. If we think this limit is
222 * not enough, we can increase the limit or try to grow the mob in runtime.
