#     kbuild: set EXIT trap before creating temporary directory
#     
#     Swap the order of 'mkdir' and 'trap' just in case the subshell is
#     interrupted between 'mkdir' and 'trap' although the effect might be
#     subtle.
#     
#     This does not intend to make the cleanup perfect. There are more cases
#     that miss to remove the tmp directory, for example:
#     
#      - When interrupted, dash does not invoke the EXIT trap (bash does)
#     
#      - 'rm' command might be interrupted before removing the directory
#     
#     I am not addressing all the cases since the tmp directory is harmless
#     after all.
