question about ev_feed_event

[Frank Kim]

Hi

I'm now implementing a program using libev on linux.  It is mainly
using ev_feed_event to deliver custom events on a thread.
But, the problem I'm faced with is that even though I sent feed event,
the listener receives the event after 1 min. (exactly 60sec).
Currently, other events are not set.  I made async object (ev++.h)
(this is used between threads) and using async object, sent feed event
to listener of the same thread, which finally called ev_feed_event.

I'm wondering why the feed event is not delivered immediately after
sending.  Async event is delivered immediately.
Is there anything I miss?

Please advise me.

thank you
Frank
