Author: asomers Date: Wed Sep 18 17:21:34 2019 New Revision: 352490 URL: https://svnweb.freebsd.org/changeset/base/352490 Log: MFC r351192, r351203 r351192: periodic: fix anticongestion for scripts run after security Revision 316342, which introduced the anticongestion feature, failed to consider that the periodic scripts are executed by a recursive invocation of periodic. The recursive invocation wrongly cleaned up a temporary file that should've been cleaned up only by the original invocation. The result is that if the first script that requests an anticongestion sleep runs after the security scripts, the sleep won't happen. Fix this bug by delaying cleanup until the end of the original invocation.
