// On Linux, signals are used to suspend/resume threads in JavaScriptCore
// When `.acquireAccess` is called, the signal might be raised.
// This causes issues with LLDB which might catch the signal.
// So we want to avoid that, we really only want this code to be executed when the debugger is attached
// But it's pretty hard to tell if LLDB is attached or not, so we just disable this code on Linux when in debug mode
