            Bug ID: 30472
           Summary: DAP "repl" evaluation can make gdb unresponsive
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: dap
          Assignee: unassigned at sourceware dot org
          Reporter: tromey at sourceware dot org
  Target Milestone: ---

gdb implements the "repl" context for the "evaluate" request
by passing the string to gdb as a command.
However, if the command is something like "continue", gdb will
simply continue -- but the DAP thread will presumably wait,
because eval_request uses send_gdb_with_response.

At least... I think this should happen.  Step 1 would be to write
a test for this.  Then, if it fails, some solution would have to
be found.  Perhaps a global flag to automatically treat continue
commands as if they had a "&" would work.
