win32: drop a py26 daemonizing hack I'm not sure what the referenced hang specifically was, but the whole test suite (with #serve) still runs on python 2.7.13. Aside from no longer prepending "cmd.exe /c", this backs out ca6aa8362f33. I'm trying to track down a rare failure of TerminateProcess() with an access error, and I've seen random extra python processes hanging around after running tests sometimes, so this might help. However, e48cb1c7a902 forces this change. Since the pid object is no longer converted to a string, the cmd.exe pid was being saved instead of the hg pid, and none of the daemons were being killed.

checkheads: simplify the code around obsolescence post-processing The 'discardedheads' return become unused and the relationship between newheads and newhs can be clarified. Our next goal here is to be able to extract the _postprocessobsolete call outside of the loop. We keep returning the 'discardedheads' because we'll start using it again soon in this series.

checkheads: drop now unused filtering of 'unsyncedheads' Now that unsynced heads are no longer in the function inputs or returns, we can simplify the code a bit.
