Subject: collectdmon: Do not block SIGCHLD.
X-Git-Tag: collectd-4.4.4~17
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=980abcf9a631fedc82920942e4c845315c49ba9a;p=collectd.git

collectdmon: Do not block SIGCHLD.

There is no reason to do so as we do not need to synchronize any waitpid()
calls. In fact, doing so was wrong because waitpid() should then return with
an error according to POSIX. This was still working so far since waitpid()
would not return until all children terminated and this is all we really care
about.
