The result of FD_ISSET() doesn't necessarily fit in a bool, though
assigning it to one might accidentally work depending on platform and which
socket FD number is being inquired of. Rewrite to test it with if(),
rather than making any specific assumption about the result width,
to match the way every other such call in PG is written.
Don't break out of the input_mask-filling loop after finding the first
client that we're waiting for results from. That mostly breaks parallel
query management.
Also, if we choose not to call select(), be sure to clear out any bits
the mask-filling loop might have set, so that we don't accidentally call
doCustom for clients we don't know have input. Doing so would likely
be harmless, but it's a waste of cycles and doesn't seem to be intended.
Make this_usec wide enough. (Yeah, the value would usually fit in an
int, but then why are we using int64 everywhere else?)
Minor cosmetic adjustments, mostly comment improvements.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
