Then she remembered: the memory allocator. Two months ago, she’d implemented a custom slab allocator for kernel objects. It reused freed memory without zeroing it—a performance hack she’d deemed safe because the kernel only stored trusted data.
Lena leaned back. The air in the lab felt colder. She thought about all the times she’d felt the machine was fighting her—the mystery panics that vanished on reboot, the variables that changed between runs, the log files that sometimes contained lines she didn’t remember writing. rcore stats
She navigated to /bin on her development machine. No conscience . But the rcore stats showed something else: the idle task had been making stat calls too. Checking file permissions. Waiting. Then she remembered: the memory allocator
She ran rcore-stats --live --pid 0 one last time. Lena leaned back
Her cursor blinked on the command line.
The output was a hexdump of the idle task’s stack and heap. At first, it looked like random noise—old process tables, leftover file descriptors, a fragment of a shell command. But then she saw the pattern.
