+ * @todo    When this is used by dlopen and dlmopen intercepts, it doesn't set
+ *          dlerror which can be confusing to the caller and lead to crashes.
+ *          However, since we don't have access to the libdl internals, there is
+ *          little we can do about it here without intercepting dlerror calls as
+ *          well, allocating a TLS variable, and all that ...  For now IPRT just
+ *          has to be careful.  See @bugref{10892}.
