Eclcompress can use too much memory #797
Description
It has been observed in logs that eclcompress can be killed due to an out-of-memory situation. In a particular case, eclcompress was run on a "xxxx.grid" file of 2.1 Gb, and when it was killed, it consumed 32Gb of memory.
This is unfortunate, and a solution could be for eclcompress to read one keyword at a time, it probably keeps everything for a file in memory at once.
