Feature Request:

Could configure etc be modified to detect if it can use
enable_extended_FILE_stdio() to allow solaris to use > 256 FD's while
still be compiled 32 bit. This is a new feature in Solaris 10 (came in
Update 4).

Some futher infomation on this:

"Programming Solutions")

http://docs.sun.com/app/docs/doc/819-2243/enable-extended-file-stdio-3c?a=view

I have no idea if this is possible or applicable to 3.x, but 3.2 is the earliest version for new features.

3.x doesn't use FILE pointers for the main I/O library (it uses unbuffered I/O instead). It only uses them for importing, and a couple of extension modules such as bz2 and zipimport.

It might still mean, though, that a Python program opening many files might fail importing a module afterwards.

Closing as Solaris is not supported as per PEP 11 and no patch was provided.
