orjson.loads
may allocate a Python object that triggers a garbage collection that invokes a destructor that callsorjson.loads
again. Or the destructor may release the GIL so a different thread can callorjson.loads
. To remain safe under such reentrancy, we need to avoid reinitializing the yyjson pool while it might still be in use. The simplest fix is to initialize the yyjson pool only once, like we did before commit e9b745e.
