cvsimport: complete the cvsps run before starting the import
We now capture the output of cvsps to a tempfile, and then read it in. cvsps 2.1 works quite a bit "in memory", and only prints its patchset info once it has finished talking with cvs, but apparently retaining all that memory allocation. With this patch, cvsps is finished and reaped before cvsimport start working (and growing). So the footprint of the whole process is much lower.
