It seems to me that a disconnection whether by the command or by a crash of gdb \
should not change exec state. That seems totally logical to me. That way a crash of \
gdb doesn't prevent reattaching and continuing to debug.

With quit though, the explicit detach is intended to restart the program so that it \
isn't paused after exiting the debugger.

The only way that I have found currently to end gdb with the program running is to \
continue execution in gdb. Then, go to another terminal and kill -9 the gdb process. \
This is not great. I would love to be able to choose which to do by only interacting \
with gdb in a normal way. Having to kill the process from another terminal is \
annoying, but it also limits the ability to script certain actions within gdb.

** [tickets:#314] quit doesn't properly detach**

**Status:** new
**Milestone:** 0.11.0

The quit command is supposed to detach (and thus continue) the inferior before \
exiting.

If one wants to disconnect without continuing the inferior, there is also a \
disconnect command.

I noticed this change: http://openocd.zylin.com/#/c/5600/1

Here's the gdb docs on attach/detach: \
https://ftp.gnu.org/old-gnu/Manuals/gdb/html_node/gdb_22.html

Here's the gdb docs on detach/disconnect: \
https://sourceware.org/gdb/current/onlinedocs/gdb/Connecting.html#Connecting

It would be lovely to have the right semantics so that quiting continues while \
disconnect does not change the execution state to match these semantics.
