    77A lazy string is an object that behaves almost exactly like a string
    88but where the value is not computed until needed.  To define a lazy

    1010appropriate arguments for that function.  Sage uses lazy strings in
    1111:mod:`sage.misc.misc` so that the filenames for SAGE_TMP (which
    12 depends on the pid of the process running Sage) is not computed when

    1313importing the Sage library.  This means that when the doctesting code
    1414imports the Sage library and then forks, the variable SAGE_TMP depends
    1515on the new pid rather than the old one.
