Hi.
Back in November,
https://sourceware.org/ml/libc-alpha/2014-11/msg00339.html, RenLin
proposed 8k for MINSTKSZ, a few days ago, off list, Szabolcs suggest
6k. The ucontext is 4560 bytes and my understanding is that MINSTKSZ
only needs to be sufficient for the kernel to deliver the signal frame
which suggests that your proposed 5k is sufficient.
OK
