Hello:

I am porting my app to Qt 5.7
When I run it, it appears on the screen,
but there is a long pause (~10 secs.) before it is responsive.
I ran it with strace and there is a point where it makes
100K calls to the poll() function, which accounts for the long pause.
I tried running it in a debugger, but the app does not exhibit the pause in that context.
This does not happen when using qt 4.8 6 (which is where I am coming from.)
Has anyone had a similar experience.
Any suggestions.

Thanks.

Bill
