util: disable floating point stat times (issue4836) Alternate fix for this issue which avoids putting extra function calls and exception handling in the fast path. For almost all purposes, integer timestamps are preferable to Mercurial. It stores integer timestamps in the dirstate and would thus like to avoid doing any float/int comparisons or conversions. We will continue to have to deal with 1-second granularity on filesystems for quite some time, so this won't significantly hinder our capabilities. This has some impact on our file cache validation code in that it lowers timestamp resolution. But as we still have to deal with low-resolution filesystems, we're not relying on this anyway. An alternate approach is to use stat[ST_MTIME], which is guaranteed to be an integer. But since this support isn't already in our extension, we can't depend on it being available without adding a hard Python->C API dependency that's painful for people like yours truly who have bisect regularly and people without compilers.
