   881  by default, signal interrupt should be disabled while making a lock file

   882 

   883   $ hg debuglock -s --config extensions.disablesig=disablesig.py

   884   abort: SIGTERM cannot be replaced

   885   [255]

   886 

   887  but in hgweb, it isn't disabled since some WSGI servers complains about

   888  unsupported signal.signal() calls (see issue5889)

   889 

   890   $ hg serve --config extensions.disablesig=disablesig.py \

   891   > --config web.allow-push='*' --config web.push_ssl=False \

   892   > -p $HGPORT -d --pid-file=hg.pid -A access.log -E errors.log

   895   $ hg clone -q http://localhost:$HGPORT/ repo

   896   $ hg bookmark -R repo foo

   897 

   898  push would fail if signal.signal() were called

   899
