Log Message:
Add cv_fdrestart() (better name suggestions welcome):
Like cv_broadcast(), but make any LWPs that share the same file descriptor
table as the caller return ERESTART when resuming. Used to dislodge LWPs
waiting for I/O that prevent a file descriptor from being closed, without
upsetting access to the file (not descriptor) made from another direction.
