Running Sublime Text 3 on Ubuntu here, Version 3.2.2 build 3211.
Problem: When running a script with Python3 or Latex, the process stays in memory after it's finished. I have to kill them manually. I discovered this after my computer froze at least twice, and it was caused by python processes from Sublime eating up all RAM and swap. Also, I had  problems with matplotlib complaining that all available resources for new windows were taken.
Expectation: when a job is finished, the process should be killed, freeing up memory.
Tests: I didn't test with other languages besides Latex or Python. I tried in Sublime build 3210 and 3209, and it had the same behavior. I tried to look for in Sublime forums and here on Stack Overflow, and I couldn't find anything related.
Thanks in advance for any help!
The problem was a "-i" flag in the build configuration for Python3... I copied this config somewhere and forgot to check. Now the processes are correctly closed!
About the Latex one, I will uninstall Latex packages and try to install them again.
