// since it is known to cause problems on the Mac. Windows has execv, but it
|
|
// is a faked implementation that doesn't really replace the current process.

// Instead it spawns a new process, so we gain nothing from using execv on
|
|
// Windows.

|
|
// updater executable wait for the calling process to exit. Otherwise, the
|
|
// updater may have trouble modifying our executable image (because it might
|
|
// still be in use). This is accomplished by passing our PID to the updater so
|
|
// that it can wait for us to exit. This is not perfect as there is a race
|
|
// condition that could bite us. It's possible that the calling process could
|
|
// exit before the updater waits on the specified PID, and in the meantime a
|
|
// new process with the same PID could be created. This situation is unlikely,
|
|
// however, given the way most operating systems recycle PIDs. We'll take our

|
// chances ;-)
