Description scott 2000-01-04 22:10:01 UTC 
rfork() with RFMEM flag generates EOPNOTSUPP when executed on an SMP kernel.  Unfortunately, the rfork() manual page does not mention this, so you have to look at kernel source to figure it out.

Fix: 

Add to rfork(2):

BUGS

rfork() with RFMEM does not currently work on SMP kernels.  In this case rfork() will return -1 with errno EOPNOTSUPP.

True for 3.X and earlier, but not 4.0-current.  It should work in 4.0-current
since about May 1, 1999.
