Because we can't determine which pool to be used other than global pool,
for the context of the error and for the life time of the svn_error_t

To learn how to use the Subversion APIs more, please see
"Using the APIs"[1] section in the Subversion book and/or the section
"APR pool usage conventions"[2], "Exception handling"[3] in chapter
"Coding and Commit Convensions" in the Subversion Community Guide.
