Comment (by mlennert):

 Actually, it is not only within. Comparing the native 'overlap' operator
 with its GEOS equivalent, the 'intersects' operator, I get significant
 time difference:


 {{{
 time v.select -c ain=boundary_municp bin=rail5000 op=overlap
 out=select_overlap
 real    0m27.363s
 user    0m12.836s
 sys     0m14.696s
 }}}


 {{{
 time v.select -c ain=boundary_municp bin=rail5000 op=intersects
 out=select_intersects
 real    1m12.190s
 user    0m56.844s
 sys     0m15.511s
 }}}
