A change in libunwind 1.8.0 (libunwind/libunwind#536) has introduced a race in one of its commits
(libunwind/libunwind@ec03043) This race causes relatively rare unwind failures when multiple
threads race for an initialization of a pipe that is used to verify that a memory address is accessible.
This change reverts the change in the affected file. Once a proper fix is made in the libunwind, this
patch would be reverted and the real fix applied.
This issue is currently blocking source build and the new exception handling enabling by default.
