Subject: CA-45104: ignore renice errors
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=0d3f4b4226fb467c21142c15c2ccecf5f6cf9708;p=xcp%2Fxen-api-libs.git

CA-45104: ignore renice errors

This patch works around a race-condition bug in forkhelpers where
the pid might not be valid anymore before forkhelpers.waitpid is
called, in case the related process is very short-lived.
