IMO, something like dont_block would be more useful for me. What I would expect
from that argument is that when it's True then `gdb.execute` would return
immediately after GDB starts running the command.

Thanks for the tip. I'll try that.


Do you think adding something like `dont_block` would be hard? Maybe I can hack
on that this weekend.
