I have done this with a trivial C program, piping the log stream stdin to stdout, putting a time stamp in front of the first character of each (not blank?) line. When C read()'s one byte at a time, it tends to force lowest latency. In ksh on /dev/fd/ systems and in bash, you can make the log file >(...), or you can manage a named pipe.

watchgnupg - Read and print logs from a socket SYNOPSIS
watchgnupg [--force] [--verbose] socketname DESCRIPTION
Most of the main utilities are able to write their log files to a Unix Domain socket if configured that way. watchgnupg is a simple lis- tener for such a socket. It ameliorates the output with a time stamp and makes sure that long lines are not interspersed with log output from other utilities. watchgnupg is commonly invoked as watchgnupg --force ~/.gnupg/S.log OPTIONS
watchgnupg understands these options: --force Delete an already existing socket file. --verbose Enable extra informational output. --version Print version of the program and exit. --help Display a brief help page and exit. SEE ALSO
gpg(1), gpgsm(1), gpg-agent(1), scdaemon(1) The full documentation for this tool is maintained as a Texinfo manual. If GnuPG and the info program are properly installed at your site, the command info gnupg should give you access to the complete manual including a menu structure and an index.
