[lwip-devel] [patch #7855] Provide alternative timeout implementation

[chrysn]

Follow-up Comment #1, patch #7855 (project lwip):

i thnk that a relative timeout scheme is better suited for timeouts, as it is
easier to work with relative values in remainder class arithmetics. (by
forming a delta, you only need a one-side comparison ("is it due yet?") as
opposed to a two-side "is this timeout in the window i'm now working off?"
comparison).

the issue with timeout drift you menioned can easily be overcome by only
adjusting the `timeouts_last_time` parameter by as much time as actually
passed. i have just submitted patch #8244, which constitutes a better solution
in my opinion.
