## Message

```
std.Progress: truncate IPC data exceeding preallocated buffers

This accomplishes 2 things simultaneously:

1. Don't trust child process data; if the data is outside the expected
   range, ignore the data.
2. If there is too much data to fit in the preallocated buffers, drop
   the data.

```
