First, some info on my system:
Mac OS X 10.9 (Mavericks) MacTex 2013 Distribution (http://tug.org/mactex/) Using Latexing package in Sublime Text 3 (might be relevant) Skim pdf viewer (as per the Latexing setup tutorial)
By chance I opened my Activity Monitor today and found four pdftex processes running, using between 90-100% CPU (my battery consumption was oddly high, that's why I checked). Sublime Text with opened tex files, but I wasn't using them or compiling them at the moment.
I closed both the Sublime Text and Skim, but the processes didn't quit. I had to quit them manually.
Anyone experienced this before? Any thoughts on what I could do to prevent this from repeating?
//edit I opened Sublime Text again and tried compiling a document. pdftex process didn't appear in Activity Monitor. My theory atm is that it was a remnant of me trying other editors (TeXWorks, TeXShop)... Thoughts?
