He objected against thread-private address mappings, not against other
implementations of thread-private storage. Of course, at first sight,
thread private mappings provide for least overhead in the application,
however on IA32 things a "slightly" different to MIPS and what is good
for MIPS is not necessarily good for IA32 and what is bad for IA32 is
not necessarily bad for MIPS. And with Linux being mostly IA32 kernel
no surpises here.
