  Changed paths:
    M io_wait.h

  Log Message:
  -----------
  [I/O reactor] do sanity check on the provided fd index

On del operation, if an index (in the fd_array) is provided, check its consistency, to avoid corrupting the reactor's data.
Upon corruption, do a backtrace and force recovery by resetting the index to -1

IMPORTANT: this is not a fix, but a detection and recovery, hoping to help identifing bad ops over the reactor's fds.

  Changed paths:
    M io_wait.h

  Log Message:
  -----------
  [IO reactor] added an enhanced logging when detecting a reactor data corruption

Use a basic/simple array to store logs to be eventually dump later if a corruption of the reactor data is detected after an io_wait_del() operation.
This is debugging only, with the intention of helping the troubleshooting some ongoing investigations.
