[Bug libc/2377] New: Deadlock between dlclose and c++ exception/unwind

["sjmunroe at us dot ibm dot com" <sourceware-bugzilla@sourceware.org>]

In this case an application is calling a library via dlopen/dlsym/dlclose. This
library created a service thread that it needs to terminate when dlclose is
called. But if the service thread takes an exception after the call to dlclose
and the libraries call to pthread_join then the service thread will hang in the
unwind code and the join will never complete.
