Correction.  It works on EL6, but not on EL5:

[CentOS 5.5 x86_64 with kernel 2.6.18-194.32.1.el5]

read(3, "2.6.18-194.32.1.", 16)         = 16
read(3, "", 16)                         = 0

[RHEL6b2 x86_64 with kernel 2.6.32-37.el6.x86_64]

read(3, "2.6.32-37.el6.x8", 16)         = 16
read(3, "6_64\n", 16)                   = 5

The issue may be specific to files in /proc/sys, because I tried
reading /proc/stat on CentOS 5.5 and it worked fine.

Cheers,

Bernard
