weird bug with parallel, RSQlite and tcltk
Hello,
I spent a lot of a time on a weird bug, and I just managed to narrow it down.
In parallel code (here with parallel::mclappy, but I got it
doMC/multicore too), if the library(tcltk) is loaded, R hangs when
trying to open a DB connection.
I got the same behaviour on two different computers, one dual-core,
and one 2 xeon quad-core.
Here's the code:
library(parallel)
library(RSQLite)
