I would just ignore any error on close in this case and treat it as a
best-effort attempt at closing the fd. The close could be successful even if an
error is reported; conversely if a signal-based profiler is used (whether they
use SA_RESTART or not) we don't want the profiler's actions to cause
application/library exceptions.
