Nice solution; only seems to work in bash as you surmised in the referenced thread, but that'll be good enough for the OP!

thread_halt_self
thread_halt_self(9r) thread_halt_self(9r)
NAME
thread_halt_self - General: Handles asynchronous traps for self-terminating kernel threads
SYNOPSIS
void thread_halt_self(
void );
ARGUMENTS
None
DESCRIPTION
The thread_halt_self routine performs the work associated with a variety of asynchronous traps (ASTs) for a kernel thread that terminates
itself. A kernel thread terminates itself (or one kernel thread terminates another kernel thread) by calling the thread_terminate routine.
The thread_halt_self routine examines the AST-related member of the thread structure pointer associated with the kernel thread that wants
to terminate itself. This thread structure pointer was returned in a previous call to kernel_isrthread or kernel_thread_w_arg and passed by
you to the thread_terminate routine. This AST-related member is set to a bit that identifies the specific AST trap associated with this
kernel thread. Based on the AST bit set in this member, thread_halt_self does the appropriate cleanup work before the kernel thread exits
from the kernel.
NOTES
A kernel thread that terminates itself must call thread_halt_self immediately after the call to thread_terminate. The reason for this is
that thread_terminate only prepares the self-terminating kernel thread to stop execution. The thread_halt_self routine completes the work
needed to stop execution of the self-terminating kernel thread by performing the appropriate cleanup work.
RETURN VALUES
None
