Ping?
This hit us again today in a different context: Chrome uses 128K thread stacks,
which is normally plenty.
But when instrumented for profiling, the counters reside in TLS, and consumed
most of the 128K stack, resulting in a crash that was hard to diagnose.
We then had to change the source before instrumented Chrome could run.
It would be nice if glibc just did the right thing, getting rid of the crash
and the need to modify sources.
