Bug Report

• Operating system: Debian Stretch
• Node Version: v8.11.3
• Dat Version: 13.11.3

Expected behavior

I'm trying to run dat on a fairly constrained VPS. I need to be able to sync about 50 GB over about 25000 files and about as many symbolic links. Files range in size from under 1 KB to over 1 GB.

Expected behavior is dat share scanning the files and sharing them without using too much memory / CPU.

Actual behavior

dat pegs the CPU at 100% and memory usage quickly grows until it gets to about ~256 MB of res memory, and then gets killed by the OS.
