Is xml-rs memory leak malloc_trim workaround still relevant?

Doesn't build if host system is using e.g. https://musl.libc.org:

   Compiling cosmic-store v0.1.0 (.../cosmic-epoch/cosmic-store)

  --> src/backend/mod.rs:95:19
   |

   |                   ^^^^^^^^^^^ not found in `libc`

It is still relevant. You could wrap it in a feature.

I don't see anything in https://github.com/kornelski/xml-rs/issues, shouldn't this be reported to upstream with a reproducer so eventually malloc_trim could be dropped from here entirely?

It's a behavior of glibc malloc rather than an issue with xml-rs
