Is there any application that extensively uses `mprotect`?

I'm looking for an application for analysis purpose that puts pressure on mprotect. I found that JIT compilers use this syscall more than others. But almost all of them (e.g., JVM, Nodejs V8) cache the compiled code at first run resulting in ignoring the mprotect calls for the rest of the execution.

My question is, is there any application (like any web server, database, HPC apps, etc) that extensively calls mprotect?

I found that Metis benchmark has some MapReduce implementations which extensively call mprotect. wc, wr, and wrmem almost dedicates over 95% of their system calls runtime to mprotect. The source could be found here

However, a production-grade application is still missing.
