Aha!  :-)  Dollars to doughnuts Solaris's "mkdir" system call is setting
errno to EMFILE when it fails.

Anyone care to verify this?  Bad Solaris, bad!  Your man pages lie! :-)

Version 2.32-BETA-1 will not directly fix this.  However, there is a
kernel setting to increase the number of open files in Solaris.  By
default, this is 256, but you can bump it as high as 1024 with
"ulimit":

	ulimit -n 1024

You can increase the hard limit by putting:

	set rlim_fd_max=8192

in /etc/system and rebooting.  (This is on Solaris 9 and untested...)
