Jenkins says this PR fails. Let me know when it is fixed and I will take a look!

[albertnetymk]

It says "out of memory" in the email, so I guess this PR is OK.

[albertnetymk]

Skipped largestream if memory is not enough. Now it seems OK.

[EliasC]

The test for available memory does not seem portable to mac:

grep: /proc/meminfo: No such file or directory
./test.sh: line 54: ((: < 3000000 : syntax error: operand expected (error token is "< 3000000 ")

[EliasC]

The rest of the PR looks really good! If the test-script is fixed (maybe this belongs to a separate PR?) this can be merged.

[albertnetymk]

Indeed, the memory test is not portable. However, it's never meant to be there. I guess I could wrap the whole thing inside a if block so that it only runs if the OS is linux; after all all mac system has enough memory to run largestream. What do you think?

[albertnetymk]

Since no one commented on this since my previous comment, I just went with adding the condition check for Linux.
