Hi,


I have a quick question regarding setting the number of threads.

- Should the IM_CONCURRENCY variable be set before building the package or
it can be dynamically changed after I build the vips package

- The steps I followed are

         - built the vips package
         - set IM_CONCURRENCY variable
         - ran the vips benchmark as follows

                      pthreadw ../inst/amd64-linux.gcc-pthreadw/bin/vips
im_benchmark bigben_2662x5500.v output.v
