commit 188759bb documented the intent
to allow recursive dlopen based on tracking ctor_visitor, but used a
kernel tid rather than the pthread_t to identify the caller. as a
result, it would not behave as intended under fork by a ctor, where
the child tid would not match.

If musl.dl.debug.dlclose is enabled, the sections of dlclosed library will not be unmapped.
Instead the mmap area will be set to PROT_NONE. If the program run into the dlclosed library
the crash log would contain the library info rather than a unmapped pc.
The param can be set by following cmdline:
param set musl.dl.debug.dlclose enable
