   I added a print method for arrow info. It looks something like this:
   
   ```
   > arrow_info()
   Arrow package version: 2.0.0.9000
   
   Capabilities:
                  
   s3         TRUE
   snappy     TRUE
   gzip       TRUE
   brotli     TRUE
   zstd       TRUE
   lz4        TRUE
   lz4_frame  TRUE
   lzo       FALSE
   bz2        TRUE
   jemalloc   TRUE
   mimalloc  FALSE
   
   Memory:
                             
   Allocator         jemalloc
   Current            0 bytes
   Max       -855217280 bytes
   
   ```
   
   The trouble is that when memory allocated is >2gb, it overflows an integer 
in the `int64_t` to `SEXP` conversion 
(https://github.com/r-lib/cpp11/issues/145). I'll see if I can work around that 
somehow.
