You can alloca one, but note that it must be small, as there isn't much stack space. A few thousand elements is probably fine though, and possibly even too many. |

@vtjnash the one thing on that test is that race condition on the sleep. Any idea on how to make that properly reliable, without risking a zombie process? |

There is a question here, printing task backtraces (or backtraces on exit regardless) requires a ct, but only because it needs a buffer. Can we alloca that buffer (malloc is probably illegal given signal context)
