You can use KProcIO which buffers the data to be written. This may be a very 
bad idea if you have a lot of data because you run the risk that you collect 
all the data in the buffer if the destination process is slow.

Another solution is to suspend the transferjob while you wait for the 
KProcess::wroteStdin signal. See TransferJob::suspend() / 
TransferJob::resume()
