like, she gets the pending stuff going. that's the whole vibe. 💅

no return value, no drama, just vibes and a channel pointer. periodt. 🫶

💖 DESCRIPTION 💖

So basically, bam_issue_pending calls the tasklet directly, which in turn starts any pending transactions. 🌀

like yes, she skips the whole "wait around" thing and just pokes the tasklet herself. the tasklet wakes up, sees the pending transactions, and starts them. slay. ⭐

ngl that "calls the tasklet directly" bit is the whole personality of this function — she doesn't queue it up, she doesn't schedule it, she calls it directly. iykyk. 🔥
