workers: handling exceptions in windows workers
This adds handling of exceptions from worker threads and resurfaces them as if the function ran without workers.
If any of the threads throws, the main thread kills all running threads giving them 5 sec to handle the interruption and raises the first exception received.
We don't have to join threads if is_alive() is false
Test Plan:
Ran multiple updates/enable/disable sparse profile and things worked well
Ran test on CentOS- all tests passing on @ passed here
Added a forged exception into the worker code and got it properly resurfaced and the rest of workers killed: P58642088

Unfortunately, non-conflicting changes, like the addition of the "c" file in p1.1 patch are reverted too. Just to say that manifest not listing "c" here is a bug. $ cd .. $ hg convert darcs-repo darcs-repo-hg initializing destination darcs-repo-hg repository scanning source... sorting... converting... 4 p0 3 p1.2 2 p1.1 1 p2 0 p3 $ hg log -R darcs-repo-hg -g --template '{rev} "{desc|firstline}" ({author}) files: {files}\n' "$@" 4 "p3" (test@example.org) files: dir/d dir/d2 dir2/d f ff 3 "p2" (test@example.org) files: a dir/d dir/d2 f 2 "p1.1" (test@example.org) files: 1 "p1.2" (test@example.org) files: a b 0 "p0" (test@example.org) files: a $ hg up -q -R darcs-repo-hg $ hg -R darcs-repo-hg manifest --debug 7225b30cdf38257d5cc7780772c051b6f33e6d6b 644 a 1e88685f5ddec574a34c70af492f95b6debc8741 644 b 37406831adc447ec2385014019599dfec953c806 644 dir2/d b783a337463792a5c7d548ad85a7d3253c16ba8c 644 ff #if no-outer-repo try converting darcs1 repository $ hg clone -q "$TESTDIR/bundles/darcs1.hg" darcs $ hg convert -s darcs darcs/darcs1 2>&1 | grep darcs-1.0 darcs-1.0 repository format is unsupported, please upgrade #endif
