Reuse the existing socket pair as a backchannel from mandocd(8) to catman(8). This is needed because catman(8) can pass messages to mandocd(8) much faster than mandocd(8) can process them: to file a new message, catman(8) does not need to do much more than one call to fts_read(3), wheres mandocd(8) needs to read, parse, and format the whole file in response. So unprocessed messages pile up in the kernel, each of them containing three file descriptors in flight, ultimately resulting in catman(8) dying with: catman: FATAL: sendmsg: Too many open files The catman(8) program cannot find out on its own how far mandocd(8) has progressed, so mandocd(8) has to tell it. Each time mandocd(8) accepts a message from catman(8), it now sends a one-byte message back. When catman(8) has the number of files in flight that it considers acceptable, it does a blocking recv(3), such that no more files get sent until at least one has been accepted. As soon as it gets one message back, catman(8) then does further non-blocking recv(3)s until they no longer succeed, to reduce the count of files in flight as much as possible before returning to sending more files. When processing is complete or aborted, catman(8) waits for the remaining files to be accepted before exiting. Debugging output related to this feature is available with -vv.
