- *	calldata is a pointer to a SkippedRequestInfoRec (include/os.h)
- *	  which provides information about requests that the server is

- *	  requests, so that's why we have to catch them here.
- *
- * Returns: nothing.
- *
- * Side Effects:
- *	The skipped requests are recorded by all contexts that have 
- *	registered those requests for this client.
- *
- * Note: most servers don't skip requests, so calls to this will probably
- *	 be rare.  For more information on skipped requests, search for
- *	 the word skip in ddx.tbl.ms (the porting layer document).
