[Mono-list] Size of thread in Mono (65MB per thread ?)

[Rodrigo Kumpera]

This sounds like a problem in your environment.

Mono, by default, creates threads with the default size of its environment.
If your setup uses 64mb stacks, that's on you.

What mono does in addition to pthread_create is to mprotect the last few
pages of the stack to implement a soft guard against stack overflow.

How much memory each pthread_create adds in your setup?
