There is an alternative. pager.c:run_pager() runs a select() to wait for data before it actually exec()s the pager. What if after the select() the process didn't exec(), but read the first line to decide what pager to exec?

Then, when pager_in_use is true, the sending process writes, say, a handler identifier which tells the pager process what to exec().
