write_tif to virtual filesystems? (crashes the Rstudio session)

[cboettig]

With other R packages binding GDAL libraries, we can both read and write to GDAL virtual filesystems provided we are using supported drivers. This is particularly advantageous in cloud environments, and generally a nice workflow that is more efficient than writing to disk and then uploading?

Would it be possible to allow write_tif directory to be a virtual filesystem, such as /vsis3? Trying this on my current version seems to lead to a segfault error that crashes RStudio.
