I am using Ubuntu 16.04 and I have noticed that from time to time a process named
MainThread appears in my machine. I couldn't find out in which program it belong to though. Besides that I have noticed that if I kill it it doesn't seem to affect my machine. The reason I am interested in killing it is because it allocates some memory I need from my RAM (about half a GB).
So, I am wondering what's this process about and if it's OK to kill it (if I am missing something here I mean)?
