- when the `gdb` features is enabled, the EINTR exit reason was always mapped to a Debug stop reason. With the new changes to the threading model, the EINTR exit reason can be a result of a cancel request. We need to first check if a cancel was requested, if not, it means a sandbox with debugging enabled was issued an interrupt request from the debugger - adds a way for a sandbox under debugging to remain attached to the debugger when a crash happens. This way the crash can be inspected. This forbids continuing execution and writing to memory and registers. Signed-off-by: Doru Blânzeanu <dblnz@pm.me>
