* 32-bit Solaris systems suffer from:
*
* - an historical default soft limit of 256 per-process file
* descriptors that is too low for many Java programs.
*
* - a design flaw where file descriptors created using stdio
* fopen must be less than 256, _even_ when the first limit above
* has been raised. This can cause calls to fopen (but not calls to
* open, for example) to fail mysteriously, perhaps in 3rd party
* native code (although the JDK itself uses fopen). One can hardly
* criticize them for using this most standard of all functions.
*
* We attempt to make everything work anyways by:
*
* - raising the soft limit on per-process file descriptors beyond
* 256
*
* - As of Solaris 10u4, we can request that Solaris raise the 256
* stdio fopen limit by calling function enable_extended_FILE_stdio.
* This is done in init_2 and recorded in enabled_extended_FILE_stdio
*
* - If we are stuck on an old (pre 10u4) Solaris system, we can
* workaround the bug by remapping non-stdio file descriptors below
* 256 to ones beyond 256, which is done below.
*
* See:
* 1085341: 32-bit stdio routines should support file descriptors >255
* 6533291: Work around 32-bit Solaris stdio limit of 256 open files
* 6431278: Netbeans crash on 32 bit Solaris: need to call
* enable_extended_FILE_stdio() in VM initialisation
