> Returns an estimate of the number of bytes that can be read (or skipped over) from this
input stream without blocking by the next invocation of a method for this input stream. The
next invocation might be the same thread or another thread. A single read or skip of this
many bytes will not block, but may read or skip fewer bytes.
> Note that while some implementations of InputStream will return the total number of bytes
in the stream, many will not.

> Not a big deal if we always use it with correct streams now, but rather dangerous.
