Add an error debug message when disassociating part of a process
execution context using unshare fails.

immediately terminated silently if unshare fails, add a debug printout
and propagate up the error code to make the failure more visible.

classes") causes the build to fail in the Chromium OS build environment,
because the return values of some function calls marked with the
__warn_unused_result__ attribute are ignored. Fix this.
