I've got no response from you to my last message (*1) in the related
thread.  So I'm not sure if you are for or against my suggestion about
undoing `in_sighandler'-related changes and just changing the order of
lock/unlock and BLOCK_INPUT/UNBLOCK_INPUT in the previous version of
BLOCK_INPUT_ALLOC/UNBLOCK_INPUT_ALLOC as follows.

#define BLOCK_INPUT_ALLOC                       \
  do                                            \
    {                                           \
      if (pthread_self () == main_thread)       \
        BLOCK_INPUT;                            \
      pthread_mutex_lock (&alloc_mutex);        \
    }                                           \
  while (0)
#define UNBLOCK_INPUT_ALLOC                     \
  do                                            \
    {                                           \
      pthread_mutex_unlock (&alloc_mutex);      \
      if (pthread_self () == main_thread)       \
        UNBLOCK_INPUT;                          \
    }                                           \
  while (0)
