Comment(by huhabla):

 I have just committed a new temporal module called t.rast.what in trunk
 (r64349 - r64351) that utilized r.what to sample space time raster  datasets using vector points. It provides three output layouts that  transforms the r.what output into row or column layouts. It can run  several r.what processes in parallel using a maximum of 400 raster map  layer in a single r.what process.

 Please have a look at it.

 Any feedback about its performance, usefulness and handling is highly  welcome.

 Improving r.what to allow more than 400 maps is simple, just edit the  fixed value in the source. But, editing this value may cause open file  handler limit problems with your OS. However, these limits can be adjusted  at kernel level configuration for Linux.

 Implementing a more intelligent file handling solution requires more  effort.
