{
  // It's possible to debug SharedWriter just like any other AthenaMP worker.
  // The following procedure provides a minimal explanation on how this can be achieved:
  //
  // Terminal #1:
  // * Run athena w/ debugging enabled, e.g. athena.py --debugWorker --stdcmalloc --nprocs=8 [...]
  // * In this mode, workers will be stopped after fork(), waiting for SIGUSR1 to be resumed
  // * Find the PID of the worker to be debugged (printed by the job in stdout)
  //
  // Terminal #2:
  // * Attach gdb to the relevant worker, i.e. gdb python PID
  // * Once the symbols are loaded, one can perform any gdb action such as setting breakpoints etc.
  // * Once ready, send SIGUSR1 to the worker to resume work, i.e. signal SIGUSR1 (in gdb)
  //
  // Terminal #3:
  // * Send SIGUSR1 to the remaining workers (easiest to use htop)
  //
  // However, note that sometimes Shared I/O infrastructure struggles with timing problems,
  // such as server/client(s) starting/stopping too early/later. Debugging can change this
  // behavior so please keep this in mind.
