+## xclip hangs in subshell environment
+
+In certain situations xclip is known to wait infinatly.
+According to this:
+
+- [Stackoverflow](https://stackoverflow.com/questions/19237559/why-xclip-bashrc-takes-much-longer-than-systemxclip-bashrc-in-ruby)
+- [Sourceforge](http://sourceforge.net/p/xclip/bugs/9/)
+
+This is related to xclip not closing stdout.
+
+To mitigate this I will try to close stdout and stderr within the
+accountmanager.sh script.
