How to increase the stack size of Julia threads?

I’m doing multiple recursive computations (Welzl’s algorithm) in parallel using Threads.@threads, producing a stack overflow. This is on latest Linux and Julia 1.7.0-rc2.
How do increase the size of a thread’s stack?

(It turns out that in this particular case the stack overflow is my fault and can’t be fixed by having larger stacks, but I’m still interested in how to change stack size.)
