// Submit a single job.
// Implementation notes:
// - The jobs use the app "single_job_PLATFORM".
//   This app has a single app_version containing the wrapper for that platform
// - the executable is part of the WU, has the sticky bit set,
//   and has a signature
// - The logical and physical name of the executable
//   (as stored in the download directory) is "program_platform_cksum"
//   where cksum is the last 8 chars of the MD5
// - The physical name of the job file is sj_WUID.xml
// - The physical names of the input/output files are name_WUID
// - a file containing the job directory is stored in
//   sj_WUID in the upload hierarchy
// - workunit and result templates sj_wu_template_WUID
//   and sj_result_template_WUID are created in templates/
// - the single_job_assimilator copies the output files to the job dir,
//   and cleans up the sj_WUID and template files
