We really need a ticket i.e. a substantive written proposal for
iflush, etc. in order to make progress on the umbrella topic that
includes it and #459.

Pavan: Please let me know when you will have something for this.

Comment (by gropp):

 The WG found this interesting, but notes that there are alternatives that
 may provide the same capability.  These include nonblocking flush.  In a
 straw vote,  iflush received 11 votes and nflush received 3; in contrast,
 nsync received 9 and isync received 4.
