There are quite a lot of test failures:
* a never before seen Windows failure in shell32:shlfolder, possibly a spurious notification from elsewhere in the file system;
* a failure in shell32:systray, possibly uID collision;
* bug 53979;
* several jscript and mshtml failures which seem to be fixed, I'm guessing by bd5ab1c6cdb;
* a recent and mostly systematic failure in mf:mf; not sure what's going on there. The only vaguely relevant commit from the period is 14743b0ffb0ce, but I'm not convinced it's related.
I'll try to look into the shell32 and mf failures, but it's clear none of them are related to this patch series.
