  .SH DESCRIPTION
- .LP
  The \fBepoll_create()\fR and \fBepoll_create1()\fR functions both create an
  \fBepoll\fR(5) instance that can be operated upon via \fBepoll_ctl\fR(3C),
  \fBepoll_wait\fR(3C) and \fBepoll_pwait\fR(3C).  \fBepoll\fR instances are
  represented as file descriptors, and should be closed via \fBclose\fR(2).
  
--- 22,31 ----
*** 47,61 ****
  Instance should be closed upon an
  \fBexec\fR(2); see \fBopen\fR(2)'s description of \fBO_CLOEXEC\fR.

  .SH NOTES
- .LP
- 
  The \fBepoll\fR(5) facility is implemented for purposes of offering
  compatibility for Linux-borne applications; native
  applications should continue to prefer using event ports via the
  \fBport_create\fR(3C), \fBport_associate\fR(3C) and \fBport_get\fR(3C)
  interfaces.  See \fBepoll\fR(5) for compatibility details and restrictions.
