## Message

```
Periodically log memory usage (#58999)

In recent memory leak reports the log was lost (OS killed Zed or forced
a reboot) or showed nothing about when memory grew, leaving us unable to
correlate growth with LSP/toolchain activity in the log. This should
help diagnose:

- https://github.com/zed-industries/zed/issues/58987
- https://github.com/zed-industries/zed/issues/58662
- https://github.com/zed-industries/zed/issues/31461

The polling costs one single-PID, memory-only sysinfo refresh (roughly
one syscall) every 30s — less than the existing per-language-server
polling in `lsp_button.rs`. So the overhead of this shouldn't affect
performance of Zed.
