[Rd] error: C stack usage is too close to the limit.

[Jeffrey Horner]

rapache version 1.0.4 and earlier attempted to turn off stack-checking 
*before* initializing R. After reading the source, it seems that it 
should turn it off *after* initializing R. I've fixed this in the latest 
release of 1.0.5.

Sorry for the confusion; it's hard to understand just from reading the 
'Writing R Extensions' manual exactly what can/should be accomplished 
before R initializes compared to what can/should be accomplished 
afterwards to influence R's embedded environment. For instance, turning 
off R's signal handling is accomplished by setting R_SignalHandlers = 0 
*before* initializing R; at least that's what the source code is telling me.

Best,

Jeff
