As
File::exists, just like obtaining a file's modification date, both are potentially blocking operations, huge file sets can slow down theuptodate-propertyanduptodate-propertiesMojos.A potential solution is to use several threads, so while the first thread is still blocked, another thread can take over the next uptodate-check. With multi-core CPUs being ubiquitous these days, such a rather small change can improve the build time considerably, in particular for huge projects with thousands of files and / or slows disks (like typically on NTFS). For single-core CPUs the drawback is neglectable.
