Toggling core.pager btwn /bin/false and less is slow the first time, then quick subsequent times. Setting core.pager to "echo no pager" gives the same behavior.

What would be handy is a windows version of strace, but the one that I found doesn't seem functional. gdb is useless for this (so far, anyway). I think it's time to sleep on this.
