On my OS X laptop, during go test -a -short std, crypto/x509 sometimes completes in a second or two; other times it takes 17+ seconds. There doesn't seem to be an in-between. Investigate once fewer fires are burning.

Can't reproduce with for i in $(seq 100); do go test -short crypto/x509; done. Close?

@FiloSottile, on a Mac? Macs often have low ulimits. But yeah, we can close. It's been awhile.

Yep on my Mac. for i in $(seq 100); do go test -a -short std | grep '\tcrypto/x509\t'; done is also 1-2s even with thermal throttling, closing.

OTOH that command triggered a kernel panic after a few iterations. Something about com.apple.filesystems.apfs, com.apple.kec.corecrypto and link. Exciting.

I'm reproducing it another day.
