Jukka,

This sounds rather strange. Most mutex locking attempts in GDAL have a timeout 
of 1000 seconds, so that might explain the "after some time". However I fail 
to see how waiting for input and mutex relate together. Or there would be a 
mutex that wouldn't be released. What is your gdaltransform command line ?
