示例1: exec

{
CHECK(!m_specs.empty(), "no procs to execute");
SignalBlocker signals;
// LockFile will be unlocked on destruction; don't do this until
// after the ProcHarvester is destroyed
LockFile lock;
// ProcHarvester will wait for all children on destruction. Since we want
// all the FDs to get closed before that happens, this must be instantiated
// before the FileMap.
ProcHarvester harvester(&signals.m_sigset);
// build a map of all the files we're going to need to open, and whether
// we need to read or write from them
FileMap files;
