> An unguarded progress handler that runs a query (for example
> `spark.registerProgressHandler(lambda **kw: spark.range(4).count() if not
> kw["done"] else None)`) recurses: the nested query reports progress, which
> calls the handler again. Since SPARK-61153 the nested query runs, so the
> recursion has no end and the native stack of the process overflows; the
> interpreter dies with SIGSEGV (exit 139) and no Python exception. PySpark
> raises RecursionError from the nested query (surfaced as
> SparkConnectGrpcException "Exception serializing request!") and the process
> survives. This change bounds the nesting of progress handlers and hooks that
> run queries, and raises RecursionError past the bound, so the process
> survives too.
