+ * is called in Sun RPC, I've come up with this work-around. It is based on
+ * the idea that if the user/caller of the xdr_to_XXXXargs functions can provide
+ * already allocated memory or provide references to memory areas on its stack
+ * just for the short-term purpose of decoding the message from XDR format, we
+ * can avoid the memory allocations in Sun RPC. This is based on the fact
+ * that Sun RPC first checks whether structure members which require memory
+ * are NULL or not and only then calls malloc. In this case, if the caller
+ * provided references are non-NULL, then the if-branches containing malloc
+ * in Sun RPC will be avoided.
+ * PS: You're not expected to understand this unless you've spent some time
+ * looking through the glibc/sunrpc sources.
