Geyser hotreload doesn't work or seems to be platform specific

[segfaultdoc]

Problem

Geyser hotreload seems to use a cached version of the dll.

Steps to Repro:

1. Load Geyser plugin
2. Change and recompile plugin
3. Reload the plugin
4. Notice it uses the old compiled version

The workaround is to rename the .so file on each compilation to correctly pull it in.

Proposed Solution

Not sure what the solution is here but here's a related issue:
mitchmindtree/hotlib#5

#[cfg(test)]
mod tests {
    use {super::*, std::fs};

    #[test]
    fn test_load_lib() {
        unsafe {
            let libpath = "/Path/to/some/existing/file.dylib";
            let libpath = PathBuf::from(libpath.clone());
            let _lib = Library::new(libpath.clone()).unwrap();
            drop(_lib);

            fs::remove_file(libpath.clone()).unwrap();
            let libpath = PathBuf::from(libpath);
            let _lib = Library::new(libpath).expect_err("expected an error");

            let libpath = "/Path/to/some/non-existing/file.dylib";
            let libpath = PathBuf::from(libpath);
            let _lib = Library::new(libpath).expect_err("err");
        }
    }
}

this test case fails on my mac. seems like issue with libloader Library

sounds like this is the crux, nagisa/rust_libloading#59 (comment)

not sure there's really anything we can do about that. the plugin would have to not link to std

Yes we also faced the same issues with grpc plugins.
