+** TODO: Place persistent recip. updates in asynchronous coproc
+2020-07-06T19:37Z; bktei> In order to update the recipient list, the
+magicParseRecipientDir() function needs to be run each buffer period
+in order to scan for changes in the recipient list. However, such a
+scan takes time; if the magicGatherWriteBuffer() function must pause
+until magicParseRecipientDir() completes, then a significant pause
+between buffer sessions may occur, causing detectable gaps in location
+data between buffer rounds.
+
+I looked for ways in which I might start magicParseRecipientDir()
+asynchronously immediately before running the data collection command
+and then collect its output at the start of the next buffer round. One
+way using the ~coproc~ Bash built-in is described [[https://stackoverflow.com/a/20018504/10850071][here]]. I'd have to
+make the asynchronous function output the recipient list to stdout
+which would then be ~read~ into the ~recPubKeysValid~ array in the
+main loop. However, for now, I'm putting the magicParseRecipientDir()
+as-is in the main loop and accepting the delay for now.
