API Development
Why must the client's long-poll timeout be set with real margin ABOVE the server's hold window, not just barely longer?
A
Exact equality between the two timeouts is actually the ideal configuration
B
Real-world network/processing latency means a timeout set with only marginal difference can still race and abort prematurely under normal jitter — comfortable margin avoids this
C
Margin has no practical purpose here
D
The client timeout should always be shorter than the server's, never longer
