The new boot1.efi boot loader is a miracle. Now I can rid myself of the UFS partition previously holding /boot.

After update from 9.2-RELEASE-p17 to 9.3-RELEASE-p24 on our production server our service started crashing with SIGSEG/SIGBUS on regular basis(roughly once a day). Investigation revealed that crashes were caused by the fact that under certain circumstances malloc may return pointer on same memory for multiple clients from different threads. We suggested that our problem was caused by thread-specific cache, so we disabled it(by adding 'MALLOC_OPTIONS=7h' to our service environment). That fixed crashes, but caused 10-100 'std::bad_alloc' exceptions every day(no 'std::bad_alloc' exceptions before that for months). Did anyone face similar issues? -- Best regards, Yury Efimochev
