The issue is Julia accept --heap-size-hint as a command-line argument and there is a mention of it in Julia's manpage, but it's missing in the documentation page.

We'll close it when the Pull Request merges ;)

Hopefully that recently added option will become redundant with the new MemBalancer (which has been merged, is expected to be reverted, fixed, than merged hopefully soon again...).
