Hi,
first of all thanks again for your contribution !
Indeed there is a solution in using windows cron, but I would like to have a
real-time solution to avoid too-much conflicts problem. And I've found it
with cygwin. So my post-commit.bat just call a post-commit.sh wherein I
close all the files descriptors when I run my background process.
Thanks for all
