Caleb Stewart	3861310d71	Even better file close handling ... For linux, we used to send one or two EOFs via C-d to the process to signal exit, however this was inconsistent. Depending on the previous input from the attacker, sometimes one was needed, sometimes two. Sometimes, we even observed more than two being needed. Instead, we now simply loop sending one at a time and checking for the end delimeter. This will be slightly slower, but avoids hangups or accidentally closing the shell.	2021-06-13 17:15:22 -04:00
